Beautiful truck! You're gonna love it. The big dually's don't get TPMS from Ford.
I have the TST TPMS on my truck and 5th wheel and glad I do. The sensor on the inner left dual quit working a while ago and I procrastinated on getting it fixed. While towing the 5er one day, the outer left dual indicated high temperature. I stopped to check things out and found the inner left had a 1/4" bolt stuck in it and no air pressure. The outer dual was carrying all the weight. If I didn't have the TPMS, the outer tire probably would have had a blowout. So, what's the odds that the only tire out of 6 without a working sensor would be the one to get punctured? LOL!
