Uhh this is bad ass! Nice work and cool idea!Part 2: Mounting the Tank & Pump
The tank is mounted to the same cross-member that the spare tire winch is mounted to. The cross-member needed a couple of 8mm holes drilled for my tank mounts to work. I used 80/20 aluminum extrusions for tank mounts. M8 holes are tapped into the sides of each extrusion (that's how they are meant to be used).

Here is the spacer I turned out of Tecamid-66 (Nylon) for the long center bolt that re-uses the winch mount on the crossmember.

Here is the full water-
tank assembly that mounts to the truck with 4 M8 bolts. The spacer shown above goes on the bolt in the center (not tightened in the pic below). The straps are bent aluminum flat bar, 2"x1/8" thick from the hardware store. Each strap is preloaded to 200lbs (yes, I stood on it before the bolt holes could line up, LOL), so that tank isn't going anywhere. Used stainless steel M8x35 bolts with a flat and spring washer. I will be keeping a close eye on the straps since aluminum can fatigue and break quite easily in this application. In the long term I would re-do these in 1/16" steel.

The water pump is mounted to the center extrusion using a simple tapped 6061-T6 plate and screws. I mounted the pump to the top of the tank to minimize road debris, damage etc. I had a NorthStar 1GPM 12v pump lying around so I used it.
