If you plan to replace your TPMS unit, the two that seem to get the best reviews from RVers are the TST 507 and the EezTire. Both have user-replaceable sensor batteries. And, both have color monitors (EezTire just released theirs in October 2019). Finally, I believe both have 3-year warrantees.
We use the EezTire unit with the B&W monitor and it works very well. I may buy one of the new color monitors (they are available separately) just because, though I doubt it will improve the usability as this unit has been flawless for a year=plus on the road. Changing the batteries on the non-flow-thru sensors (which we prefer) is quite easy...and, they last a long time. Ours have lasted almost 2 years (counting the time prior to installing them on the coach).
