Got back and needed to catch up but here is my update:
I upped the tire pressure to 50 PSI in the rear and 45 in the front. I also dropped one hole to lower the tongue and the whole thing kind of dialled itself in.
Don't get me wrong, I still knew I was towing and I still felt the semi's, but according to a dealer I stopped at, I should expect that in just about any vehicle. Drove all the way back with no fear or issues.
Moral of the story, listen to people who offer tuning advice before they suggest you move up to a bigger truck.
In any case, this is my last post here, just bought a Georgetown 364TSF and taking delivery January 30th.
Thank you for all the help.
