I looked around before we purchased a TPMS 3 yrs ago & it seemed there wasn't a big difference between any of the various manufacturers. Everyone seemed to like the one they bought.
I have used the EEZTIRE T515/SP TPMS for several years and they work great without a signal booster. It's about 50' from the receiver on the dash to the rear wheels of the Wrangler Unlimited. I just changed the batteries in all 10 transmitters on the wheels after more than 2 years. Pretty good service.
We are looking at down-sizing to the Isata 3 & want to transfer the the TPMS from the class A. So for Bob's issue of dropping a rear read out, I wonder if there is something in the MB chassis that blocks the signal?

Oh, one other thing. The TPMS saved me from a catastrophic tire failure once. Glad I had them.
