Hi everyone,
Based on the great information here (thank you to everyone that posted their numbers), I think I'm going to go with the Silverado 3500HD DRW truck. My calculations are for the GM trucks; not sure what might be different with a Dodge or Ford.
From the information posted by fellow forum members thus far, the average pin weight is 2,781 lbs. Assuming that (in rough numbers) a full tank of diesel fuel weighs about 250 lbs, the 5th wheel hitch is about 200 lbs, and I have 800 lbs of people (including the dog) in the truck, there isn't really much left to think about in the decision.
The 2500HD max payload is 3,059 lbs, minus the approx. 1,250 lbs of people, fuel, and hitch leaves only 1,809 lbs for the king pin; that puts the average 3055RL hauler overweight by 972 lbs and the lightest unit posted over by 766 lbs.
Going over the calcs once again for the 3500HD SRW, I have max payload is 3,592 lbs, minus the approx. 1,250 lbs of people, fuel, and hitch leaves only 2,342 lbs for the king pin; that puts the average 3055RL hauler overweight by 439 lbs.
Finally, going over the calcs for the 3500HD DRW, I have max payload is 4,728 lbs, minus the approx. 1,250 lbs of people, fuel, and hitch leaves 3,478 lbs for the king pin; which would put the average 3055RL hauler under by 697 lbs and even accommodates Sailorand's 3,240 pin weight with 238 lbs of payload capacity to spare.
I realize that the vehicle manufacturer's engineers have likely put in some wiggle room above their figures, but I guess I'd really rather not venture into the twilight zone, both for safety and for peace-of-mind.
Thoughts?
