I have a 2004 F250 6.0 and a 28ft 1982 Layton Skyline bumper pull trailer. The trailer hooks up to an anti sway hitch on the ball set up. Total weight of truck and trailer is just over 12k ( no water, and about a half a tank of diesel fuel ). The trailer alone weighs just under 5k lbs. I am planning on towing the trailer from Utah to Oklahoma. Will this be a problem to pull that far? That will be the furthest I've ever pulled the trailer, as typically I stay in an around the major salt lake region here in Utah.
