I was exactly the OP. I bought a 39' TT after pulling 5th wheels. I knew my truck was more than capable, (15 F350CC 4X4), I towed it home with just a ball in 35-40mph crosswind. what should have been a 5 hour trip turned into a 7 hour trip at 55 instead of 70mph.
Before we took the trailer out again I got an Anderson hitch that is not super great with weight distribution (that is not a necessity) but is great at sway control, and super easy to install, hook up and get correct adjustment for sway control.
I have put over 7k on trailer since and I am very happy with my set up.
