LandAirSea 54 is the best trailer GPS tracker for most owners because it combines IP67 weatherproofing, a built-in magnet, fast alerts, and flexible plans. TKSTAR TK905 with a prepaid SIM is the lowest-cost option at about $5/mo.
The best GPS tracker for a trailer — often searched as a trailer tracking device — has to survive rain, heat, and months of sitting in a driveway. This guide compares 6 trackers across utility, boat, and cargo trailers on what makes them hold up.
Quick Picks by Trailer Type
| Trailer situation | Best pick | Why it fits | Next step |
|---|---|---|---|
| Utility or cargo trailer parked outdoors | LandAirSea 54 | IP67 shell, built-in magnet, and fast movement alerts make it the safest default. | Check LandAirSea on Amazon |
| Storage trailer where monthly cost matters most | TKSTAR TK905 | BYOD prepaid SIM keeps the ongoing cost low, if you accept the rougher app. | Check TKSTAR on Amazon |
| Hidden install inside a hitch receiver or small cavity | Tracki 4G | The small body hides easily; the magnetic battery box helps with long idle periods. | Check Tracki on Amazon |

- All magnetic-mount — no wiring, no drilling, tool-free attachment under the frame
Choosing the Right Trailer GPS Tracker
Trailers sit outdoors for weeks or months. They don’t have an engine to recharge a tracker, no OBD port to plug into, and no climate-controlled cabin. That makes trailer tracking different from car tracking in three ways.
Battery life is the biggest factor. A car tracker plugged into an OBD port never dies.
A trailer tracker runs on its own battery, and a dead battery means zero tracking. Battery expectations range from short live-mode runtimes to multi-month saver setups; the standard TKSTAR TK905 is manufacturer-listed for up to 30 days of standby.
Any tracker lasting less than 2 weeks forces you into a recharging routine that most owners eventually quit.
Weatherproofing matters. Trailers park outside in rain, snow, and 100+ degree heat. Look for IP67 or higher. The LandAirSea 54’s IP67 shell and the TKSTAR TK905’s weatherproof housing are both designed for outdoor trailer exposure.
The Tracki 4G is rated IPX6, so treat it as rain-ready rather than submersion-ready.
Alert speed determines theft recovery. A stolen trailer can be miles down the road within the first hour, and recovery odds fall fast — the National Insurance Crime Bureau reported that cargo theft losses topped $1 billion in 2023. A tracker updating every 3 minutes gives you 16 location pings in that window. A tracker in battery-saver mode updating every 4 hours? Zero useful data during a theft.

We recommend the LandAirSea 54 to most trailer owners. Its built-in magnet attaches directly to a steel frame, and the IP67 rating means rain, mud, and road spray won’t cause damage.
Mounted under a steel trailer frame, the LandAirSea 54 reports its location through the Silvercloud app.
LandAirSea’s current public plan table starts month-to-month service at $19.95/mo for 3-minute updates, with faster intervals costing more and long prepay terms lowering the monthly equivalent. Its official specs page states that battery life runs 1 to 3 weeks depending on update interval, plus a low-power mode for longer idle periods.
2. Tracki 4G
§ Review summary
Tracki 4G — at a glance
≡ Specs
- Network
- 4G LTE worldwide
- Subscription
- $9.95/mo flat
- Battery
- 5 days real-time / 60 days saver / 6 months with box
- Water rating
- IPX6 (rain only)
- Weight
- 1.8 oz
- 2-year cost
- About $269
✓ Pros
- +Smallest tracker here at 1.8 oz, fits in palm or trailer hitch receiver
- +Magnetic box accessory ($20) supports multi-month saver use
- +Flat $9.95/mo subscription, no tier confusion
- +60-day battery in saver mode without accessory
- +4G LTE with worldwide carrier support
✗ Cons
- −IPX6 only (rain-rated, not full submersion)
- −Short live-mode battery requires frequent charging
- −Magnetic box accessory adds $20 to the device cost
§ Buy if
- ·You need the smallest possible footprint (fits inside a hitch receiver or storage compartment)
- ·Magnetic box supports long idle periods when you don't need frequent updates
- ·Flat $9.95/mo without tier paralysis suits a single-trailer owner
- ·Your trailer is sheltered enough that IPX6 (not IP67) is acceptable
At just 1.8 oz, the Tracki 4G is the smallest tracker here. Its live mode is the high-drain setting; saver mode and the magnetic box are the better fit for a trailer that sits.
That isn’t great for a trailer sitting idle, but the magnetic box accessory (about $20) changes the equation. It turns the Tracki into a saver-mode storage option when you don’t need frequent updates. At a flat $9.95 per month with no tiered pricing, it’s one of the best value combinations for long-term trailer tracking. Read our Tracki GPS tracker review for app screenshots and accuracy data.
3. Optimus 3.0
Fleet operators should look at the Optimus 3.0 (about $27). It offers unlimited geofences and an SOS button. If you run trailers across multiple job sites, you can set a geofence around each location without hitting a cap.
Optimus positions its default reporting mode as a longer-runtime setting, with slower intervals stretching it further. At $19.95 per month, it costs more than other options here, but the unlimited geofences make it worth the premium for commercial fleet operators managing 5 or more trailers at different sites. Our Optimus 3.0 review covers the app interface and geofence setup.
4. Family1st Portable
The Family1st Portable (about $30) follows the usual charge-app-mount setup for a magnetic tracker. Battery life is a multi-week class rather than a set-and-forget season, and the app interface is one of the cleaner ones in this category. At $21.95 per month, you’re paying roughly double what LandAirSea or Tracki charge, which puts the two-year total at $557. See our Family1st tracker review for a full cost breakdown.
5. SpyTec GL300
Need 5-second updates? The SpyTec GL300 (free with a plan) has the fastest update interval on this list. It also works internationally on 4G LTE, which helps for trailers crossing the US-Canada or US-Mexico border.
At $34.95 per month (or $22.95 on the annual plan), it’s among the priciest options. Most US-based trailer owners will get comparable results from the LandAirSea 54 for less.
6. TKSTAR TK905

- +5000mAh battery listed up to 30 days on standby
- +Strong built-in magnet for steel trailer frames
- +BYOD SIM gives you carrier flexibility
- +Weatherproof housing for outdoor trailer mounting
✗ Cons
- −App is basic, no web dashboard
- −Manual BYOD SIM activation adds setup friction
- −Geofence setup less smooth than LandAirSea or Tracki
§ Buy if
- ·Lowest 2-year total cost (~$175) is your hard constraint
- ·Trailer sits in storage; quarterly recharging fits your routine
- ·You're comfortable with a basic app and manual SIM activation
- ·Real-time 3-second tracking is not required for storage scenarios
The TKSTAR TK905 is built for owners who want to spend as little as possible each month. Instead of a proprietary subscription, it uses a bring-your-own SIM card. A prepaid data SIM from T-Mobile or AT&T costs about $5 per month, and the 5000mAh battery is manufacturer-listed for up to 30 days of standby between charges.
The app works but looks like it was designed in 2015. No web dashboard. Geofence setup isn’t as smooth as LandAirSea or Tracki.
For owners who don’t mind a rougher interface in exchange for $120 per year in total operating costs, the TK905 is hard to beat. You’ll need to buy and activate a SIM card yourself, but the long-term savings are substantial compared to any subscription-based tracker on this list. Read our TKSTAR TK905 review for SIM card setup instructions.
Trailer GPS Tracker Cost Comparison
The device price gets all the attention, but the subscription is what determines your real cost. Here’s how the numbers stack up over two years:
| Tracker | Monthly | 2-Year | Battery |
|---|---|---|---|
| LandAirSea 54 | $19.95+ month-to-month / lower with prepay | $269+ | 1-3 wks |
| Tracki 4G | $9.95 | $269 | 5d-6mo* |
| Optimus 3.0 | $19.95 | $506 | Up to 1mo |
| Family1st | $21.95 | $557 | 2-4 wks |
| SpyTec GL300 | $34.95 | $839 | 2.5 wks |
| TKSTAR TK905 | ~$5 | ~$175 | Up to 30d standby |
*Tracki with magnetic box accessory (~$20 extra)
How Long Do Trailer GPS Tracker Batteries Last?
Battery life depends almost entirely on update frequency. Real-time tracking (updates every few seconds) drains a battery in days, while battery saver mode stretches that same cell to months.
Here’s how the batteries compare by mode:
| Tracker | Real-Time | Saver |
|---|---|---|
| LandAirSea 54 | ~1 wk | ~3 wks |
| Tracki 4G | 5 days | 60d (6mo w/box) |
| Optimus 3.0 | Few days | Up to 1mo+ |
| Family1st | ~2 wks | ~4 wks |
| SpyTec GL300 | ~2 wks | ~2.5 wks |
| TKSTAR TK905 | ~3 wks | Up to 30d standby |
For trailers sitting in storage for weeks, the TKSTAR TK905’s 5000mAh battery keeps ownership cost low, but it’s a 30-day-standby class tracker rather than a multi-month set-and-forget unit.
For trailers used weekly on job sites, the LandAirSea 54 on the middle-tier plan can fit a weekly recharge routine with daily location updates. If your trailer has a 12V power source (like running lights wired to a tow vehicle), you can hardwire the Optimus 3.0 with a separate cable kit for continuous power. Tracki’s 4G coverage documentation confirms that all major US carriers support the data protocols these trackers use.
Trailer GPS Tracker Installation Guide
Most trailer GPS trackers use a magnetic mount, so installation is tool-free when the frame has a clean steel surface. If you’re looking to track the tow vehicle itself, our best GPS tracker for trucks guide covers OBD and hardwired options for pickups and fleet trucks.
Step 1. Wipe dirt and grease off the metal surface with a rag. A clean mounting spot keeps the magnet from shifting at highway speed.
Step 2. Pick your location. The best spots are inside the frame rails or behind the tongue jack. You want steel (not aluminum), protection from direct road spray, and a spot that isn’t visible from a casual walkaround. The C-channel frame rail tends to work best on utility trailers.
Step 3. Press the magnetic side firmly against the clean steel, then tug it to confirm the magnet won’t shift before you drive.
Step 4. Open the tracker app and verify the location shows correctly. Drive around the block to confirm updates come through. Boat trailer owners can mount under the frame rail too, though saltwater exposure demands at least IP67 water resistance.
For enclosed cargo trailers, you have more options. The tracker can go inside the trailer itself, stuck to a metal wall or hidden in a storage compartment. An enclosed metal trailer can weaken the GPS and cellular signal, so mount the tracker near a wall seam and verify it updates in the app after install. Trailer GPS trackers locate over the satellite network the U.S. government documents at GPS.gov.
Owners hauling livestock should read our dedicated horse trailer GPS tracker guide. A long-idle equestrian rig leans harder on standby battery than a weekly-use cargo trailer.
Can You Track a Trailer Without a Monthly Fee?
Yes, but with trade-offs.
BYOD SIM card. The TKSTAR TK905 doesn’t require a proprietary subscription. Buy a prepaid data SIM from any major carrier and insert it. A T-Mobile IoT SIM costs about $5 per month, putting your two-year total at roughly $175 versus hundreds more for a full-service tracker with faster update intervals. Our guide to GPS trackers without monthly fees covers more BYOD options.
Apple AirTag as backup. Costs $29 with no subscription, but it relies on nearby iPhones to report location. No real-time tracking, no geofencing, no movement alerts.
One-time purchase trackers. A few companies bundle a year of data into the device price ($100 to $200 upfront). Update intervals are slower and apps are bare-bones, but you avoid monthly payments entirely. See our no-fee car GPS tracker guide for more options. The FCC’s enforcement page on GPS jammers also explains why signal-blocking devices aren’t a realistic threat to modern GPS trackers, which should put theft concerns about jamming into perspective.
If theft recovery is your primary goal, a LandAirSea 54 plan with frequent updates gives you movement alerts that a BYOD SIM or AirTag can’t match at the same speed. Readers who tow behind a motorhome should also skim our RV GPS tracker guide for chassis-specific install notes on 12V hardwire vs OBD-II.
Bottom Line
The LandAirSea 54 is the best GPS tracker for most trailer owners. It’s waterproof, magnetically mounted in seconds, and flexible enough for both weekly-use trailers and theft-recovery monitoring.
For the lowest ongoing cost, go with the TKSTAR TK905 and a prepaid SIM. That’s about $5 per month with a battery listed for up to 30 days of standby, putting the two-year total near $175 before taxes and carrier changes.
Across utility, boat, and cargo trailers, these two trackers cover every common use case. If you need the smallest tracker for hidden placement, the Tracki 4G with the magnetic box accessory gives you 6 months of battery in a unit that fits inside a trailer hitch receiver. Check our motorcycle GPS tracker guide for concealed mounting ideas that also work on trailers.
FAQ
Can you put a GPS tracker on a trailer?
Yes. Most trailer GPS trackers use a magnetic mount that attaches directly to any steel frame. Press the tracker against the inside of the frame rail and it holds with a built-in magnet. No wiring or drilling needed when the mounting spot is clean steel.
What is the best GPS tracker for a utility trailer?
The LandAirSea 54 is the best option for utility trailers. Its IP67 waterproof rating handles rain, mud, and road spray, and the built-in magnet sticks to steel frames. Current public plans start at $19.95/month for month-to-month service, with lower equivalent pricing available on longer prepaid terms.
How do you track a trailer without power?
All 6 trackers on this list run on internal rechargeable batteries. Battery life ranges from days to months depending on the tracker, battery pack, and update frequency. The TKSTAR TK905 has a 5000mAh battery that is manufacturer-listed for up to 30 days of standby. For permanent installations, the Optimus 3.0 supports hardwire connection to a 12V power source.
Do GPS trackers work on trailers in rural areas?
GPS trackers need cellular coverage to send location data to your phone. In areas with no cell signal, the tracker records locations internally and uploads them when coverage returns. If your trailer is stored somewhere with zero cellular service, you won’t get real-time alerts until the trailer moves to an area with coverage.
How much does trailer GPS tracking cost per year?
Annual costs range from about $115 (TKSTAR TK905 with a $5/month prepaid SIM) to $300+ for faster-update subscription trackers. The LandAirSea 54 starts at $19.95/month on month-to-month billing, but long prepaid terms can lower the monthly equivalent. Device prices run $30 to $55, but the service plan is what changes total ownership cost.
Can a thief disable a trailer GPS tracker?
A thief would need to find the tracker first. Magnetic trackers hidden inside frame rails, behind tongue jacks, or inside enclosed compartments are hard to spot during a quick theft. GPS jamming devices exist but are illegal in the US under FCC regulations. The best defense is hiding the tracker where a visual inspection won’t reveal it.
Is an AirTag good enough for trailer tracking?
An AirTag works as a backup but not as a primary trailer tracker. It costs $29 with no monthly fee, but it relies on nearby iPhones to report location. There’s no real-time tracking, no geofencing, and no movement alerts. If your trailer gets stolen and taken to a rural area with few Apple devices, the AirTag may not update for hours.
