I have 2 pick-up trucks now. One is a small Chevy Colorado (new) and the other is a 3500 diesel dually. Both have their advantages. However, I'd never attempt to tow a 13,500 pound loaded 5er with the little Colorado, but the advantage of the short bed is great to parking or driving anywhere like a car or SUV.
But, when it comes to towing a 5er, the dually 1 ton can't be beat! Stable, powerful, robhust, and they are made to carry and pull heavy loads, without blinking an eye.
My bed is 8 feet 2 inches (inside length). My 5er hitch, not a slider, is positioned such that I can turn truck and trailer 90 degrees and the trailer will not hit the cab of the truck. I know, that's not good on trailer tires at all, but the ability to that eliminates any potential of accidentally turning too much an whacking the cab.
Log bed for towing a 5er, no debate in my book. Dually for stability. 1 ton for power. Crew cab for comfortable room and space inside the cab, the ability to carry almost anything, and have extra comfortable seating room for passengers. My truck has the full front seat. It's split, but still a full front seat. Lift the arm rest and 3 people, with seat belts, and sit up front and 3 adults can comfortably sit in the back seat. Lift the back seat up and the entire space is now cargo, floor to ceiling.
If you have the option, I advise going this way. As far as towing goes, you'll never regret this decision.
