The 2014 RAM 2500 and 3500 are coming with 20 inch wheels which sport Firestone Transforce 265/70R 20 tires rated at 3660 and the 285/70 at 3860 LBS at 80 PSI. This should eliminate the DRW SRW issue. Pin load is no longer a factor given this. Rams GCVWR is very capable of towing most everything Heartland manufactures. Dont want a dually, don't buy one.
