Truck Wheel Base VS Trailer Length

[offroad]

34' 9" GVWR-8849lbs on the TT, 155" WB SRW on a 3/4 ton TV with Equalizer 4 point.
No sway, issues in windy conditions or while being passed by Semi's.
My last three RV's were 5th wheels so I know what tows well.

TT setup can take a bit of time to get just right though, and a 1/2 ton could be different. Our dealer mounted the Equalizer's brackets on the trailers tongue too short, instead of moving the breakaway switch. After curing that, I've been completely happy.

I'm a noobie to towing, just bought a 32' 5th wheel and 2014 F150 Supercrew (145" WB) Ecoboost. I get the chucking and the swaying and the vibrations which come on bad roads. I had 3 successful trips taking my time and taking it easy. I will be getting new tires for TV and 5ver, and airbags put in the truck bed. I haven't towed anything in over 17 years since being in the military, (soldier 1st, truck driver 2nd, then your trained job) but it came back to me pretty fast maneuvering it.

20 feet of travel trailer for the first 120 inches of tow vehicle wheel base plus a foot of trailer for every 4 inches of wheel base over 120 inches is what I have learned in my googling on the topic.

I inherited a 35' TT with GVW of 7630lbs. Should I get a long bed F-350 single rear wheel or a short bed? I know it's overkill on the weight, but I want to get something that I can upgrade trailer later to something heavier if I decide to later on.

If there are restrictions to length or surface area usually mentioned in owners manual pulled a 31” really 35’ 9” with Crewcab Tundra then crewcab f150 both short beds had equalizer w/d and sway never any problems

Limiting factor will always be your payload capacity.

Funny took my F250 wheelbase of 141 divided it by 5, got 28.2 the EXACT length of my 5er...kind of eerie
