One Monitor. Every Vehicle Protected.
Travel Trailers & Fifth Wheels
Travel Trailers & Fifth Wheels
The most common blowout victims. OEM trailer tires are notorious for failing without warning — and you can’t feel it from the cab. MARCALAR catches pressure drops and temperature spikes before they turn into roadside disasters.
Boat Trailers
Boat Trailers
Salt, sun, and long sits between launches wreck trailer tires from the inside out. MARCALAR monitors the damage you can’t see — so your next launch day doesn’t start with a blowout on the ramp road.
Horse & Livestock Trailers

When you’re hauling live animals, a tire failure isn’t just inconvenient — it’s dangerous for everyone involved. MARCALAR gives you the early warning that lets you pull over calmly, not in a panic.
Utility & Work Trailers
Utility & Work Trailers
Heavy loads on rough roads push tires to their limits. MARCALAR reads up to 144 PSI and monitors temperature in real time — built for the trailers that work as hard as you do.
RVs & Motorhomes
RVs & Motorhomes
Your rig is your home on the road. A single tire failure can mean thousands in damage and days stuck waiting for repairs. MARCALAR supports up to 18 sensors — enough for your motorhome and your toad.

No factory TPMS? No problem. MARCALAR gives your old workhorse the same tire monitoring tech that comes standard on new trucks — for a fraction of the cost.

Your Journey Ahead
See what the towing experience is like with Marcalar
-
Phase 1
Unbox & Install
Screw on your sensors by hand, and mount the solar monitor on your dash. Total time: 5 minutes. No tools, no pairing, no app download.
-
Phase 2
The First Drive
Pull out of the driveway and watch every tire's pressure and temperature appear on screen in real time. That knot in your stomach you didn't know you had? It's already loosening.
-
Phase 3
The Pay Off
A slow leak. A hot tire. A pressure drop you never would have felt from the cab. MARCALAR catches it, you pull over calmly, and what could have been a $5,000 blowout becomes a 10-minute fix at a gas station.
-
Phase 4
Tow Like a Different Person
No more thumping tires at rest stops. No more white-knuckling on the highway. No more wondering what's happening behind you. You just drive and MARCALAR watches what you can't.
Trustpilot reviews
Excellent 4.8 / 5

Caught a slow leak before disaster
Halfway through a 6-hour tow to the campground, the MARCALAR beeped — my passenger-side trailer tire was dropping pressure. Pulled into a gas station, found a nail, plugged it in 10 minutes. Without MARCALAR I would have been on the shoulder with a shredded tire and a damaged fender.
-
No more pre-trip anxiety
I used to white-knuckle every mile towing my fifth wheel. Now I glance at the monitor and know every tire is good. The peace of mind alone is worth ten times the price. Wish I had this years ago.
-
Finally, no batteries to deal with
I went through two other TPMS systems before MARCALAR. Both had sensors that went dead after a few months because the coin batteries died. Solar sensors? Genius. Set it up once and forget about maintenance forever.
-
Saved my travel trailer on its first trip
Brand new trailer, brand new tires. Twenty miles in, the MARCALAR caught a temperature spike on the left rear. Turned out the bearing was going bad and overheating the tire. Caught it before a blowout that would have destroyed the whole wheel well.
-
My wife insisted we get this
After our first blowout on I-40 — two hours on the shoulder, traffic screaming past, kids in the truck — my wife said we’re never towing again without a monitor. MARCALAR was the simplest one to set up and it just works. Every trip, every time.
-
Best $50 I ever spent on my RV
I’ve spent thousands on my rig and this little monitor might be the smartest purchase of all. Knowing my tire pressures and temps in real time while I drive — no phone app, no subscription — it’s exactly what this should be. Simple and reliable.
