Pick up was stock. No gear hunting on highway except for going up hill.

55 to 60 miles per hour its around 17 to 1800 then at 70+ 2200 and up.
I currently have a 285/70-17 wheel and tire combo on it, when I bought it it had the 245/70-16 wheels and tires, changed them for towing stability not so much for looks. I've also got a camper shell/cap on the bed. I have looked at the profile of the truck versus the trailer and there is a lot of flat trailer showing around the edges, one of those bubbles may be in the cards. I also stumbled across the manifold modification a while back, if I can find another manifold to modify i'll give it a try. I appreciate all of the input I have received on this matter and I am going to give some of this a try. Thanks
