Hello and welcome to just answer Dodge. This is not too difficult to do. You will remove the fuel filler neck fasteners where they mount to the bed, the 8 bolts (4 on each side) where the bed bolts to the frame (15 mm bolts) and the rear wiring harness connectors that connect the lights. You will also need to remove the spare tire winch bezel (2 phillips screws). Then get about 4 guys (2 on each side) and lift the bed off of the truck. You should not need to do anything with the exhaust. It will stay connected to the frame. Here is some information from the factory service manual for you to look at also. Hope this information helps, and let me know if you need more assistance with this.
