I'm having trouble understanding the RV Tow Check 2.0 calculator. I am looking to upgrade both truck and a 5ver and want to know what the correct towing capacity is of any new truck I buy before shopping for the trailer. I'm looking at a 2015 F250, 4x2, crew cab, 6.7l Turbo diesel with a 3.73. I find the GCWR is 31,900, the GVWR is 9900, I set the GVW at 6800 (curb wt.), gear and cargo at 500 and passengers at 500. At a 20% pin weight the calculator shows such a truck would have a 9500 lb. towing capacity for a fifth wheel. Am I interpreting this right? That seems low for what I have observed on the road and its well below Ford's published 23,600 lb maximum loaded 5th wheel weight for such a truck in their towing guide. Thanks in advance.
