I have a 2016 2WD Expy Limited with tow package and I tow a 35ft 7,500lb TT with a Blue Ox WD hitch. I went through a couple hitches before settling on the Blue Ox and it makes the drive much more enjoyable. I also understand that our trailer is big but I with the Blue Ox I have not had any sway issues or trailer wagging. There are 2 issues that I have encounters and not sure how to approach:
1. While towing I am totally engaged with the truck, paying attention to every squeak, bump, and noise. Sometimes the truck feels like it is shifting weight from side to side. It isn't sway, it is not a horizontal motions but more like a rocking motion. My wife has yet to notice but I do. I am thinking either bilstein shocks in the rear or an aftermarket swaybar seems like the best bet but would like opinions as I don't have any experience with either. I have owned/own 4runner, tacoma, and LX470 so am very familiar with bilstein but have never installed their products.
2. I have relatively new load range E tires (~8k miles on them) with max air pressure of 80 psi and I typically air them up to 60 - 65psi while towing. About 90% of the time while towing the above trailer the TPMS dash light will go off sometimes as soon as 45mins other times hours into a trip. The rear passenger tire will be 10 - 15 psi higher than the other 3 tires which remain very close to each other. I understand that heat is the only think that can increase the tire pressure (assuming no little monsters are on the wheel inflating it as we drive) but the higher pressure tire doesn't feel hotter or any different that the others. I don't think it is a TPMS because I check all the tires with the same gauge. This may be related to the above issue but not sure. I have 3 kids and one does ride in the back on that side however is a 60lb kid going to make that much difference? I always air up the tires the night before the we leave and I always check pressures right before we leave.
Any thoughts or advice would be greatly appreciated.
