Over the past year I've made several trips pullin a 27' TT with my 1991 1/2 ton Suburban. Wouldn't think of hitchin up without my sway control or load leveler bars. Last week I bought a 2003 F250 Crew Cab With a 7.3L diesel. I can't wait to hook up and hit the road. My question is this.... With the weight of the big engine in the front and the beefy suspension in the rear is it still necessary to use the load leveler bars? I can see where the sway control bars are still important but can this bigger tow vehicle handle the load safely without the leveler bars. What do you think???
