Thanks for every ones advice and the TT is a 2018 puma 31FKRK and I measured it and its 37 feet not 43 feet. The truck is a 2014 Ford F150 XLT with the 6.2 engine with 3:73 gears I ordered the truck this way. The truck pulls it fine and handles it fine. I am asking about air bags to help with the sagging of the truck and yes I have a weight distribution hitch and yes it is set to the correct settings according to the instructions from manufacture. Also the dry weight on the side of the TT is 8121
