Looking for any experience with aftermarket valve stem cap style that have a long enough range and aren’t junk. I’d like to not spend hundreds, but will if it’s absolutely necessary.

Id like the simple cap with 12 plug in reader if they don’t fail.

 

I know there are a bunch of threads on this and I’ve read through them. It’s a lot of arguing back and forth about why they’re needed or not needed and no links posted to any current units.

if anyone has any experience with a decent aftermarket TPMS for a travel trailer I’d love to hear about it. I’d like the type that plugs into 12v and uses replacement caps as the monitors.

Most of the Amazon offerings don’t have the range needed for a trailer, seem to be junk, or are priced incredibly high.

 

Many on the RV Forums claim that they lose signal often, causing false alerts. I'm like you as well, I'd spend $100 to know if I picked up a nail and slowly loosing pressure going down the road.

 

That statement is the exact reason I want one. Being that my Airstream is a single axle, it seems even more important.

 

Have a look at etrailers site. They have a few that may be good.

 

I do a lot of RV forum reading. The is a 'go-to' TPMS for RV use. You will rarely find any user complaining about it.

Personally, I've been using the for 2 years without issue. I did not want yet another monitor to view and the Smart TPMS runs off an app on my iPhone. The app does NOT need to be monitored or be the 'active' open app in order to receive alerts. The provided receiver (which just sits in the truck cab) emits an audible tone when either the tire pressure or temp falls below your selected threshold. I can then take a look at the app to see what's up.

Both systems will provide pressure and temp monitoring and will come with a repeater that will be mounted to the trailer.

I cannot recall losing signal with my system. Mounting the repeater in the recommended manner/area is essential. Mine is mounted to the A-frame of my 33' travel trailer. The valve stem transmitters 'talk' to the repeater which acts as a middleman, forwarding the signal to the receiver in the cab of the truck.

Of course a TPMS is not going to prevent a sudden blowout - you will likely hear and/or feel you've had one prior to the TPMS even going off. The TPMS main purpose is to notify you of a leaking tire, loss of pressure....allowing you to catch it before it goes flat.

I find the accuracy of the readings to be excellent. I sure prefer checking my tire pressures on the app prior to leaving the campground instead of squatting on the ground and checking the tires manually with a gauge.

Any of the highly regarded systems is going to run you $300-$400.

 

I appreciate the thorough reply with the links. As well as your expertise with the matter. I will look into them. I’ve seen a lot of the Tireminder brand show up as being decent. One set I found was $150 and was for just a single axle trailer.

Would you or anyone consider this one any good? https://www.etrailer.com/TPMS-Sensor...PMS-TRL-2.html

I don’t want to waste time with multiple types and have poor experience. I just want it to tell me if I have a slow leak.

Thanks again.
