I had Husky Portable Containment build me a custom 95g freshwater bladder and a 165g wastewater bladder, that were configured to sit side by side in the free space in my truck bed at the time.

OP, although I feel like you've had the same/similar thread recently, along the lines of n0arps setup, you can get ballast bags and pump for a wakeboat fairly reasonably. Would work the same as this for fresh and gray water quite handily.
