I know this is old but I have an 04 2500 that i would like to turn into a DRW. The reason I want it DRW is for the stability of towing my 33" bumper pull RV. I dont intend to pull more than truck is rated for or even carry more in bed, just want the four tires on the ground for towing. I have heard that the axles were the same on the only issue was weather the brake caliper would fit with the wheels. Is this what you did by using a spacer? Nothing else was needed? Hate to sound so dumd on this. Thanks, Louis
