Which truck would be better for my TT

I have pulled and carried both 35 foot trailers and 35 5th wheels,with slides, i like the f 150 but all ways got a 3/4 ton for that size trailer.Even then at times I could have used a 1 ton dually, for stability. In the old days we pulled 35 foot trailers with 6 cyc. chevy's and v/8 flathead fords, ---- BUT - the weigh was not even close to today's travel trailers.I use my 1/2 ton for travel trailers up to 28 foot and 22 foot 5th wheels.Over that get a bigger truck.
