Should have purchased a Ford F250 or Ram 2500, bigger is better when towing. Towed a 2013, 33' Cougar TT, 85k GVWR with a 2010 F150, CC 2WD, 5.4 w/3:73 gears. Don't recall WD hitch hook-up but did have sway bars. This was OK but right on the edge. With that much length and weight, you will feel the semi's coming up on you as they tend to suck you toward the center line, BE PREPARED!
Welcome to the forum and good luck - safe travels.
