Appreciate the insight, thank you.

Do current model GM 1500, 2500 and 3500 crew cab trucks share the same cab (in terms of dimensions)? If yes, does anyone know if a 36 gallon 2500/3500 gas tank (not diesel) would swap/fit in place of the 24 gallon 1500 gas tank? I've looked under the 1500 CC and there appears to be a lot of unused space in front of the 24 gallon tank (presumably for the DEF tank for the 3.0 diesel engine).
