Best to move up to a RAM 3500 SRW for towing a fiver around. You are right about the pin weight, most fivers run around 2,000 to 2,500 pounds of pin weight, too much for a 2500.How are you guys handling the hitch weight? Most of the 5er's I've looked at have pin weight in excess of the payload with any kind of weight in truck. They tell me that the pin weight is 20 to 24% of the trailer weight.
