This guy has nothing on the setup I saw pulling out of a repair shop the other day. The guy was towing a 2006 30' Montana 5th Wheel with a single cab, long bed, 2wd Ram 1500.
Apparently he was at the shop getting new springs installed on the truck to keep it off the bump stops. As he pulled out of the bay, it may not have been quite on the bump stops, but the front of the truck was still shooting for the stars.
The scary part is I overheard him saying he used to drive long haul trucks for a living. I was glad he was long gone before I got back on the road.
