I posted this question at the end of another TPMS thread over on the wheel and tire board, but figured I'd try my luck over here since this board seems to get a little more traffic and since my question isn't really relevant to the original thread.
I am curious if anyone knows what the range of the TPMS transmitters are, and if the system in the truck is capable of tracking 8 sensors instead of just the five?
Here's the reasoning.
I pull a travel trailer and would like to have a monitor in each tire on the trailer without having to buy a stand alone system and having to sintall some other kind of monitor in the cab. The trailer axle is roughly 17 feet behind the rear axle of the truck. and then the spare on the trailer is about 10 feet beyond that.
I guess, if the spare was too far away I could do without that. Then also would the truck light up at me when I was running without the trailer? That would of-course only matter if the system in the truck can monitor additional sensors, and they would still be in range?
While I'm asking questions, what is the expected life of the batteries in the sensors, and are they user replacable, or is that one of those things that I would get raped by the dealer for?
Thanks for any input
