I pull at 42 foot 19,500 lb toyhauler with no issues with my short bed megacab. I use a non-sliding B&W Companion. The shape of the trailer's nose and the amount the trailer's hitch sticks out in front of the trailer have a lot to do with it. I hardly ever get close to my cab. I have lots of trailering experience, so that helps. A friend of mine had a megacab with a Fusion TH and he hit his cab a few times taking out the back window. Like I said, the shape of the nose has a lot to do with what you can comfortably tow with. My Megacab is a 2010 and it is solid as a rock with my loaded camper.
