Add in 4x4 to that. I know the GVWR was 9900, what was the GCWR in 2005 for a Quad Cab 4x4 auto shortbox 3500? In the newer rams 06 and on the long boxes are rated much higher than the short boxes in GVWR as in 12,200 vs 9900. I have a 2005 2500 short box that is only rated at 9000 and 20000 respectively. If I ever need to go heavier up to 3500 weights I am going to go with airbags in the rear since other and the spring rates the two versions seem identical.
