I am getting ready to replace my 2003 2500HD 8.1 V8 Allison Extended Cab SB with a 2008 2500HD Duramax Crewcab SB. I am towing a 2006 3400RL Monty.
The curb weight for the 2008 4X4 CC is 5983 and 5847 for the extended cab with the same package. Difference of 136 lbs. The max trailer weights for the same setups are 13,600 and 14,300. Difference of 700 lbs. Same type of differences in the 2wd and 4x4 crew cab weights.
Can anyone tell me what causes the bigger difference in max trailer weights?

I can't answer your question, but I can tell you that your curb weights are incorrect. If I had to guess, I'd say they are for a trucks with gas engines. Using the CC as an example, 9200 (GVWR) minus 5983 (your curb weight) equals 3217. There are NO 3/4 ton D/A 4 x 4s with that much cargo capacity. It is about 1000# too high. Look at the Tire and Loading Information sticker on the left rear door pillar, it will give you the cargo capacity for that truck to the nearest one pound. Subtract that number from 9200 and that will be your true empty weight.
This is more confusing information from GM.

So you disagree with GM's figures? Here is a
chart from their website. Looks like the figures quoted were on the money. I think Brad probably had the right answer for the question. More capacity for occupants.
