Just came back from Bethpage last weekend and got to use my tst system for the first time and vary pleased with it but a couple of questions,, one is why would the temps vary so much between drivers side and passenger side exp driver side would be 74 degrees and passenger side would be 82 degrees about 7or 8 degree difference on the truck and rv both the next is will the air pressure be ok going to about 86 psi and that's on all the tires on both tv and rv and my rv is 40 ft but I didn't hook up the repeater and it did fine without it is this something I should go ahead and put on ? We are going to the outer banks next week so I will try it again thanks. ⛄️⛄️⛄️⛄️ Jeff
