Lippert is one of the biggest names in RV components, and its Tire Linc system ships as original equipment on many new RVs. If your RV came with Tire Linc, you already have tire pressure and temperature monitoring built in ā displayed right on your smartphone or through CarPlay.
That OEM convenience is real. For a lot of owners, Tire Linc is the tire monitoring they didn't have to think about.
But Tire Linc is a TPMS ā and this guide is about what a TPMS doesn't monitor. Here's the upgrade that matters: axle temperature.
Lippert brings OEM polish to tire monitoring.
If your RV ships with Tire Linc, you have a competent TPMS out of the box.
Here's the limitation: Tire Linc monitors your tires. It's a TPMS, and that's its entire scope.
The average roadside wheel-end failure costs $1,800ā$4,000 in repairs, towing, and downtime. And a tire blowout is just one failure mode. A failing wheel bearing generates heat from the hub outward ā detectable before catastrophic failure, but only if you have a sensor on the axle.
Tire Linc has no axle monitoring capability. Like every TPMS-only system, it can't see what's happening at your bearings.
There are also practical limits:
Tire Linc does what it was designed to do ā monitor tires. The question is whether tire monitoring is enough.
The TrailerWatchdog TWD-1500 was designed around a simple question: what if one system monitored everything that can fail on your trailer's running gear?
That means axle temperature and tire pressure ā both feeding into a smartphone app with trend intelligence.
The TWD-1500 runs $395ā$595 depending on your trailer configuration and sensor count.

If your RV already has Tire Linc installed, there's a natural question: why pay for another system?
Here's the honest answer. If Tire Linc is already there and you only want tire monitoring, you already have it ā there's no urgent reason to replace it.
But if you tow a boat trailer, a horse trailer, or heavy equipment ā or you simply want to know what's happening at your wheel ends, not just your tires ā the TWD-1500 adds the one thing Tire Linc can't: axle temperature monitoring with trend intelligence.
And there's a practical angle: Tire Linc caps at 6 tires. If you tow a larger setup, or you want expandable coverage, the TWD-1500's mesh array gives you room to grow.
Keep your Tire Linc if:
The TWD-1500 is right for you if:
This comparison isn't really "Lippert vs TWD." It's "OEM TPMS vs. complete wheel-end monitoring."
Tire Linc is a competent, convenient TPMS ā and if you have it, that's real value. But bearing and axle failures don't show up on a tire-pressure system. They show up as heat on the axle ā the exact thing the TWD-1500 was built to detect.
Tire monitoring is important. It's just not the whole picture.
The TWD-1500 gives you complete wheel-end coverage ā tires and axles ā in one system, on your smartphone, with trend intelligence that catches problems before they strand you. Starting at $395. Less than one roadside service call.
If Tire Linc is already there and you only want tire monitoring, you're covered. The TWD-1500 adds the one thing Tire Linc can't: axle temperature monitoring with trend intelligence. If you tow a boat, horse trailer, or heavy equipment ā or just want complete wheel-end coverage ā it's a meaningful upgrade.
Yes. They monitor different things ā Tire Linc covers tires, the TWD-1500 adds axle monitoring. They don't conflict, and the TWD-1500 installs independently with magnetic hub sensors.
The TWD-1500 uses its own smartphone app over Bluetooth 5 mesh. It's designed for the phone, not CarPlay ā but it gives you axle monitoring and trend intelligence Tire Linc doesn't offer.
The mesh array is expandable. The standard TWD-1500 supports up to a tandem-axle trailer; the Commercial & Fleet model supports up to 8 axles. That's more headroom than Tire Linc's 6-tire limit.
Axle sensors are magnetic ā 30 lbs of holding force ā so you place them on the hub and they stay. Tire sensors screw onto valve stems. No drilling, no wiring, no permanent modifications. Most owners are up and running in 15ā20 minutes.
Lippert Tire Linc is a competent, convenient OEM TPMS ā and if your RV came with it, that's real value for tire monitoring.
But tire monitoring is one piece of the picture. Axle temperature is the measurement that catches bearing and hub failures before they become roadside disasters ā and that's the gap a TPMS can't close.
The TWD-1500 gives you both ā tires and axles, one system, one app. Starting at $395 ā less than one roadside service call.
