stripit I agree it is a personal choice. A brother-in-law had a blowout and almost lost his motorhome. He now has a tpms system.
I thought we had a tpms system on our Sprinter 3500 based motorhome but a dual tire blew out and I didn't know it. Took it in to have all the tires checked and ended up with a new tire as the old one was completely ruined. I didn't have an accident but I think I was lucky to be driving with only one tire working on the one side. That was when I discovered no tpms and I bought this model as soon as possible. I am primarily interested in the range ends for both pressure and temperature so the small monitor works just fine for me.
