I know in the mid to late 90s, gm made a "heavy half" which had the 1500 motor, with beefier axles from the 2500, I don't think they make them anymore, I have driven a few trucks for work, and friends trucks for fun, something about gm puts a smile on my face, and you don't have to chop off your foot when you do the spark plugs like my friend did on his ram, (16 spark plugs).
Came close to buying a 06 chev 1500 ext twice, but the dealer wouldn't give me enough money for my jeep, low enough price on the truck, and I didn't really want to trade the jeep anyway, but they are nice trucks that's for sure!
Enjoy your Chev.
