Well have that frame and so far so good (Fingers crossed). They are pretty well maxed out as shipped. I would steer VERY clear of any dealer who suggests a frame hitch on an ultra-lite as FR has stated that any modifications to the frame after it leaves the FR factory would void your warranty. I would find out if the hitch mount will be a FR option or a dealer add. If it is a dealer add; I would ask for something in writing from Forest River (NOT THE DEALER).
