TPMS in Class A Motorhomes

I see no reason for the government to get more involved in my RV experience then they are. What happened to pre trip inspection and checking your tire pressure during and after your travel? It would seem to me this system is designed for drivers that don't do the proper maintenance or pre trip checks. I would never depend on a government mandated gadget for my safety. JMHO.

I agree 100%. There is a large number of RV owners who do not check their tire pressure until the TPMS sends an alert. If they have long tire valve extensions, like on rear duals, the temperature warning is almost useless. I asked one owner what he had his TPMS set for and he told me that once the pressure drops 10% below his minimum, it will send a warning. That means that he may be driving many miles with the tire pressure below the minimum pressure needed for his load, which is not good for that tire but is also now overloading his other dual tire that has to pick up the additional load.
Checking tire pressure is a hassle for those that want to make it a hassle. For me it takes a few minutes. I know that when leaving an RV park in the morning I very very seldom see anyone checking their tire pressure.
The TPMS system in an RV is a lot different than the ones in an automobile that very seldom is loaded to the maximum allowable weight. Most RV's travel at close to, or over, the maximum gross weight at all times and the tire pressure should never be allowed to drop below the minimum pressure required to carry that load.
The funniest thing I heard from one RV owner when he heard his TPMS alarm going off on a cool morning was..."I don't worry about it. Shortly after I start driving the heat will cause the tire pressure to rise and the alarm will go off." Smart! :B
