I read through the forum and cannot find my exact issue, so I apologize if this question has come up elsewear. I recently got a 17' TT Forest River 17bhse, towing with a 2015 f150 with a class 3 hit...
where are your tanks, often potable water is up front. filling the tank can add weight just don't forget to refill it and empty the waste tanks in the rear before the journey home. can also add larger propane tanks, more battery or some bikes to the front.
make sure the trucks tires are aired up too. lastly if your nose high that will hurt you get er level if not slightly nose down.
