Hey, Phil!
The UWS 75-gallon combo transfer tank part # UWS39XR would be perfect for your truck. Your truck is 66.4" wide so you will still have some room on the sides of the tank. I do want to also mention that the tank is Federal DOT compliant and National Standard of Canada compliant for Diesel usage, as well other Class 3 fluids within Packing Group III.
