is the height of 2500 & 3500's all the same, it seems like the reg cabs have more clearance than the ext cab and crew cab, my 94 2500 looks tiny sitting next to my friends 01 2500 and iv got 265s. im in the market for a used dmax, i like the reg cab but their hard to find and the other 2 just seem too low in stock form, maybe its just my imagination

The HD 2500/3500 trucks that started in 2001 sit 2" higher than the regualr 2500's because the frame is 2" taller. I don't think the cab length makes a difference.
