Thanks for the response. I'll look for that one. Gear shop really leaned towards the full floater for towing my trailer. The trailer is around 4,000lbs and the 56 is about 3,200lbs. Although the van is rated GCWR of 13,500lbs it seems highly overated. I had this same problem towing a camping trailer back in the 90's. Chuck in NHPS: anyone coming to Columbus have one of these?
