Ed Newman told me that the departure angle of the 27 foot rear bed model is 6.5 degrees. That seems very small to me.
Has anyone had trouble with there rigs bottoming out?
Rollers only make the departure angle smaller.
Thanks

With my 26 RSB, I only drag on fairly steep transition surfaces. I keep my air bags at least inflated to 2/3 max pressure, and often carry an off road motorcycle on back. The drag roller wheels are an asset, and cushion the occasional contact with the road surface. I don't consider it an issue. A test drive should address your concerns. I launch a boat on steep ramps with no problems (except seeing the boat & trailer).
If you want to raise the motorhome rear slightly, you might consider using 235 x 85 tires, and gain over an inch at the rear axle. They have a higher weight carrying capacity, they are about a half inch wider and a few pounds heavier, and would have the effect of gearing you higher. The Tire Rack tables list 245 x 75 wide tires as a Ford E option, so clearance between the dual 235 tires should be OK, if my math is correct, since 245s are wider yet than the 235s. A tire expert should be consulted, of course.
My previous 23' Chevy G30 motorhome would drag much worse, I am surprised I never got billed for some of the gouges I put in the roads with that one.
