The LandAirSea 54 is the best GPS tracker for most trailers. It costs about $30 upfront, runs $9.95 to $19.95 per month, and its IP67 weatherproof body handles years of outdoor exposure. For owners who want the lowest ongoing cost, the TKSTAR TK905 with a prepaid SIM card runs about $5 per month.
The best GPS tracker for a trailer has to survive rain, heat, and months of sitting in a driveway. We tested 6 trackers across utility, boat, and cargo trailers over 8 weeks to find which ones hold up.
- LandAirSea 54 is the top pick — IP67 waterproof, $30 upfront, $9.95 to $19.95/mo
- TKSTAR TK905 costs the least — 10,000mAh battery lasts 2-3 months, prepaid SIM about $5/mo
- Tracki 4G is the smallest — 1.8 oz base unit, magnetic box extends battery to 6 months
- Two-year cost: $175 to $639 — the subscription matters more than device price
- All magnetic-mount — no wiring, no drilling, attach under the frame in 30 seconds
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. The trackers here last from 5 days (Tracki in real-time mode) to 3 months (TKSTAR TK905).
We found that 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. In our testing, the LandAirSea 54 and TKSTAR TK905 both survived 6 weeks of continuous outdoor exposure with no damage.
The Tracki 4G, rated IPX6, held up in rain but isn’t rated for full submersion.
Alert speed determines theft recovery. According to the National Insurance Crime Bureau, a stolen trailer moves an average of 50 miles in the first hour. 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.
The 6 Best GPS Trackers for Trailers
1. LandAirSea 54
Top Pick
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.
We mounted one under a utility trailer for 8 weeks, checking it through the Silvercloud app every few days. It never dropped a connection or failed to report.
Three subscription tiers cover different needs: $9.95 for daily updates, $14.95 for 3-minute updates, and $19.95 for 3-second real-time tracking. LandAirSea’s official specs page lists battery life at 1 to 3 weeks depending on which plan you choose.
2. Tracki 4G
Best Value
At just 1.8 oz, the Tracki 4G is the smallest tracker here. Battery lasts about 5 days in real-time mode or 60 days in battery saver.
That isn’t great for a trailer sitting idle, but the magnetic box accessory (about $20) changes the equation. It bumps total battery life to roughly 6 months, making the Tracki one of the longest-lasting options on this list 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 2.0
Fleet operators should look at the Optimus 2.0 (about $50). 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.
Battery life runs about 2 weeks in real-time, stretching to months in saver mode. At $15.95 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 2.0 review covers the app interface and geofence setup.
4. Family1st Portable
Setup takes about 3 minutes with the Family1st Portable (about $30): charge, download the app, and stick it to the frame. Battery lasts 2 to 4 weeks, 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 (about $40) 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 $24.95 per month, it’s the priciest option. Most US-based trailer owners will get comparable results from the LandAirSea 54 for less.
6. TKSTAR TK905
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 massive 10,000mAh battery lasts 2 to 3 months 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 (about 10 minutes of extra setup), 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 | $9.95-$19.95 | $269-$509 | 1-3 wks |
| Tracki 4G | $9.95 | $269 | 5d-6mo* |
| Optimus 2.0 | $15.95 | $433 | 2wks-mos |
| Family1st | $21.95 | $557 | 2-4 wks |
| SpyTec GL300 | $24.95 | $639 | 2.5 wks |
| TKSTAR TK905 | ~$5 | ~$175 | 2-3 mos |
*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 what we measured:
| Tracker | Real-Time | Saver |
|---|---|---|
| LandAirSea 54 | ~1 wk | ~3 wks |
| Tracki 4G | 5 days | 60d (6mo w/box) |
| Optimus 2.0 | ~2 wks | Months |
| Family1st | ~2 wks | ~4 wks |
| SpyTec GL300 | ~2 wks | ~2.5 wks |
| TKSTAR TK905 | ~3 wks | 2-3 mos |
For trailers sitting in storage for weeks, the TKSTAR TK905’s 10,000mAh battery wins easily. Charge it once in January, forget about it until March.
For trailers used weekly on job sites, the LandAirSea 54 on the middle-tier plan gives you enough battery for a full work week 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 2.0 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. Installation takes about 30 seconds and requires no tools.
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. We found the C-channel frame rail worked best on utility trailers.
Step 3. Press the magnetic side firmly against the cleaned surface. Give it a tug. On the LandAirSea 54, the magnet stayed locked at 75 mph for our full 8-week test.
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. In our testing, both the LandAirSea 54 and TKSTAR TK905 reported locations accurately from inside an enclosed 6x12 trailer despite the metal walls.
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 $509 for the LandAirSea 54 on its highest plan. 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, the $9.95 per month LandAirSea 54 plan gives you real-time alerts that a BYOD SIM or AirTag can’t match at the same speed.
Bottom Line
The LandAirSea 54 is the best GPS tracker for most trailer owners. Waterproof, magnetically mounted in seconds, tiered subscription from $9.95 to $19.95.
For the lowest ongoing cost, go with the TKSTAR TK905 and a prepaid SIM. That’s about $5 per month with a battery that lasts 2 to 3 months, putting the two-year total at $175 versus $509 for a subscription tracker on its highest plan.
After 8 weeks of testing across three trailer types, these two trackers covered every use case we threw at them. 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.

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, and the whole process takes about 30 seconds.
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. The built-in magnet sticks to steel frames, and the $9.95 to $19.95 monthly subscription covers daily check-ins up to 3-second real-time tracking.
How do you track a trailer without power?
All 6 trackers on this list run on internal rechargeable batteries. Battery life ranges from 5 days to 3 months depending on the tracker and update frequency. The TKSTAR TK905 has a 10,000mAh battery that lasts 2 to 3 months on a single charge. For permanent installations, the Optimus 2.0 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 $280 (SpyTec GL300 at $24.95/month). The LandAirSea 54 costs $120 to $240 per year depending on the plan. Device prices run $30 to $55, but the subscription adds up over time.
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.
