Recently purchased a 32‘ trav trailer. My Durango did not come with a tow package so the RV place where we were purchased from installed the whole set up. The problem I have is they used a class 4 Mopar receiver and a class 2 EZ hitch to the camper. The TT is only 5400 lb it’s an ultra lite. This thing swayed Violently at about 65 mph, slowed down to about 50 of course it smoothed out but the “PreLoad“ couldn’t have been set right. I had to call someone with a 3500 Ram to tow this thing back to the RV Dealership. When I went to unhook the RV one bar was preloaded so much I had to use a 50” pry bar to get it loose. I have pulled many trailers including a 30’ pace enclosed for my race car years ago but that was with a 1500 series P/U. Another issue I had I couldn’t see anything beside me what kind of extendable mirrors are yall using to pull a TT. i know this all sounds crazy but when they deliver your TT to you at 8 pm be cause it took 5 hrs longer than it was supposed to and it’s dark and they close at 6 on a Saturday your stuck like chuck.
