Wow, there is allot of opinions out there. To the suggestion of hydrolic ramps, no but I my entertain the use of a wedge at the front to drive up on therefore putting the wheeler at an angle and shortening the length needed in the bed.
As to the other concerns...I do believe it will put more stress on the TV hitch. I will watch that for any bending or stress. The TT weighs in at #4260 dry and about #5000 the way I have it loaded. I have to believe manufactures have some kind of liability to only make accessories that are within the specs of their equipment. Otherwise we would have law suites. Thanks again for all the great input.
I will carry the old one with me and if I have to make a switch on the road, I will.
