With no rear bumper or roll pan, the tank is going to show- no way around it.
I am using my original '65 Suburban tank in my '65 LWB, so it'll only hang down as low as it did in the 'Burb.

You will still be able to mount a reciever type hitch, as they bolt up to the outside of the frame rails, or on the bottom of the frame rail.

I personally would never run another in cab tank again- after a close call in a wreck, just not willing to cover myself in spilled fuel if I cannot exit the truck.
