As I am looking for a 2500 new, I found that the payload of both Chevys and Rams is lower when they have a diesel engine than gas engine. Why is this? How does that affect the available payload for ...
Well diesel engines weigh more, but will pull more. The same is true for 3500's a gaser will have more payload, but the diesel will have a greater GCVWR.
Simple solution is to go SRW diesel. Usually about $300 to $500 more, but you gain payload if you need it.
