What did DRV do to beef up the frame on your unit?
They added square tubing, I believe it was 2 or 3 inch cut and was welded from the front axle to the rear facia. The hitch was then welded to this as well as the other 15inches of rear frame. At the time it was their remedy to allow an M/C lift. I believe the frame is strong enough but that didn't address the over-load on the axles. It was a $750 option and although we don't use it to carry the bike we will be double towing alot so it does provide a little peace of mind.
