I've got one of those ancient, inferior 7.3 trucks, and it's a rclb to boot. Drug our 26' TT up to dfw, then down to the coast, and back home (roughly 600 miles round trip), just hangin off the ball. No sway control, or weight distribution. It probably weighs about 7k-7500 loaded up (bedroom in the nose, with a slide), dropped the ass end of the truck about 2", and it pulled it at 75 straight as an arrow. Occasional side wind off a big truck, but nothing that two fingers on the wheel couldn't control. My old ccsb truck pulled my 24' and 32' enclosed car trailers without any aid all over. And it did not sway at all like my regular cab would want to.
If you have any experience towing, and a set between your legs, you will be okay. If you wanna be a girl, throw on all the weight distribution, sway control, etc for a "feel good", and roll. You won't need it.
