RV without a WD hitch

If It was me doing the towing, I think I'd be fine with it for the one trip then go the E2 route. I really can't speak for you though. An 11000 pound trailer is no light weight and I'm going to think it'll have a somewhat porky tongue weight as well. Without a WD hitch you are relying completely on the weight distribution in the coach to balance out the load. I don't think you'd have a lot issues with the tongue weight other that the occasional whoop-de-do when you come across a bridge/overpass crossing at any kind of speed on a highway...that tongue weight(w/o your E2)will push down hard on the ass-end of the pickup lightening up the front axle and steering. It's about recognizing what the hazards are due to the physics, and how you are going plan and work around them. And as the previous poster commented, make sure the ball and the ball mount are rated for this duty.
