I am considering a TPMS (tire pressure monitoring system) for my motorhome and 'toad'. Does anyone have experience with a TPMS? Good or bad? Any particular brand over another? I am considering the Tire Minder "TMG 400C" which can monitor up to 22 tires for pressure and temperature. It also allows for battery replacement and not the complete sensor. Any comment on this brand?

I use the Truck System Technologies tire monitoring system. It's the only system I've had so don't have anything to compare it to. Seemed to get good ratings when I researched it originally and it wasn't as expensive as others. I've had it for about a year and already replaced the batteries in four out of eight sensors. No idea how long they were on the shelf before shipped to me. Ordered them through Amazon. They were simple to install and the batteries weren't that difficult to change.  Nice to have since I'm not too good at checking the tire pressure myself all that often.
