Looking at the weights I am going to say it's a 6.0L gas truck, which does put the tow rating at 10,000 and GCWR at 16,000. 4.10's would bump it to 18,500. What I thought was interesting was that going to a 3500 (SRW or DRW) doesn't change the GCWR.

I agree with Coach, the floor plan is very important so make sure it's not a compromise too far in either direction.

Going to a 3500 DRW truck doesn't get you any more GCWR than the 2500 Truck!!!!!:E You mean to tell me that a 3500 DRW truck only has a GCWR of 16,000#, same as the 2500??
I find that really hard to believe...Even if you're talking about a 6.0 gasser in a 3500 DRW truck, I find it extremely hard to believe that GCWR would be the same as on a 2500...if so, why even bother to manufacture a 3500 SRW or 3500DRW with a 6.0 gas engine in it? Why waste a perfectly good rear axle and put FOUR wheels on the back of it if it only has a puny 16,000# GCWR??? That's amazing, don't think I've heard of that before, but again, if it's a gasser, maybe GMC was covering themselves for the limitations of the 6.0 and the tranny it came with..curious, very curious.

Keep in mind GCVWR, is based on the ability to move a certain weight with a given drive train. The same drive train in a larger TV will not make a difference in what it can move. AH64ID posted that his on a 3500 is 1,000# more than the same 2500 with same drive train, maybe, just maybe they add a little for bigger brakes or GVWR.
That said the GCVWR is really a rating of the ability to move a given weight, that is why as the gear ratios get numerically higher (4.10 from a 3.73 will tow more) the GCVWR goes up.

It is possible that AH64ID's 3500 has a lower gear ratio, that the 2500 he is comparing it to.
