Ram 3500 SRW have over 4k payload..firestone tires are rated to over 3600 each...with a 7k rear axle and 12400 GVWR. After running all the numbers time and time again and weighing mine at a scale, I am going with a 16500 GVWR toy hauler (12500 empty) with a 3000-3200 pin. The only time I would be over 14klbs in the TH would be with quads or rzr in the back, lightening up pin weight a couple hundred lbs...if your numbers come in somewhere around that I think you would be fine...but then again I have never towed with a DRW either...
