Hi Dave,
Oh your gonna love running the wiring to a rear antenna. What a joy.
First, The 365 wheels do have enough room to mount the sensor, however it may be that you have a very short valve stem and may need to change it out. The stem I found on my coach were long enough but the side of the sensor does rub on the inside surface of the hole in the wheel. The dual tires will need an extension for the inside tires.
You absolutely need a rear antenna. The instructions from the factory are quite clear on that.
I had Newell install the TPMS when I purchased my coach and the SilverLeaf dash was able to read the pressures. At the time they only installed a front antenna and it simply would not read the tow vehicle and sometimes not even one or both of the tags and one side of the duals. On rainy days I could loose all of the rear tire readings, Duals, Tags and tow.
Running a coaxial cable for the rear antenna is uncomfortable if you don't have a pit to work from. The cable runs from the control module behind the dash down one of the feed tubes that bring wires below floor level. If you crawl under the coach and look behind the fiberglass front cap and forward of the suspension you will see how the wiring drops through the feed tubes. From that space you bring the wires into the air compressor compartment then join the cables running rearward and feed it through one of the tubes that bring the wires rearward. Eventually you will come out into the electronics bay and from there you can feed into another tube running back to the drive axels.
I placed my second antenna above and just behind the drive axels. I still have a bit of difficulty reading all of the tow vehicle tires as the engine is in the way no matter where you place the antenna. Going rearward of the engine means you may not read the duals which I think is more important to keep track of. On a good day I get all tires reading most of the day.
Plan on a few days to pull this off as you're going to need to calm down every few hours or so, as doing this on your back can be really uhm... challenging.
Best Regards,
Mike
