Too bad Ford, and the others, don't post the payloads of those trucks along with that useless gigantic max tow weight. They'll all be short on payload looonnng before to they tow that max weight in a rv.
A 1/2 ton V6, or any motor, with 14000lb TT with a tongue weight of 1800+lbs (13%) before anything else is added or 5th wheel at 3000+lbs (22%) pin weight , hope I'm not driving next to them.
That max tow weight for trucks & the rv manufacturers posting useless dry weights do nothing but confuse newbies coming into the towable RV lifestyle.
