I think if you reread the posts, you might be confusing my comments with others. I've consistently maintained that Ram trucks with diesels weigh more than those with gas engines. For SRW trucks, payload is less for diesel trucks than gassers since the weight of the engine is part of the overall Gvrw.
If you compare 2 trucks,one with diesel and 1 with gas, the diesel will weigh more overall but its payload will be less. Other factors that affect Gvrw and payload include options - lightest trucks with greatest payloads tend to be regular cab, 2wd, short beds. Adding 4wd, more options like bigger cabs reduce payload.
So, I think we're on the same page. But, I don't agree that adding options doesn't change Gvrw. You state that by adding options and trim levels, you increase curb weight and reduce payload without changing gvrw. By definition, gvrw includes curb weight so if it goes up, gvrw goes up accordingly.
I'm not sure how or if OEMs can manipulate gvrw - it weighs what it weighs.
