Question:
I have a 2023 gmc 3500 with a shot bed. I also have the gooseneck package with the puck system hitch in the bed. I also have the adapter plate to hook up the fifth wheel hitch that I pull a fifth wheel camper with. Would this tank work with my set up ? Thanks

Hey Rob! I can't imagine it wouldn't fit your setup given the width of the tank. However, you can double check to make sure you have space by measuring. The DeeZee Truck Bed Auxiliary Tank # DZ91752X measures 59-1/2" long x 9" wide x 19" tall. If you want it to feed directly into your fuel line you will also need the Connector Kit for DeeZee Truck Bed Auxiliary Tank # DZ97960.
