Here's my LandcruiserPhil Puma mount modified to hold two 3.5gal Waterbrick containers. This mount, on the passenger side, works perfectly for this given how the mounts are nearly centered underneath the platform. Each fill Waterbrick weighs 28lbs according to their web site. That's the same as a Puma compressor. Two are right at 56lbs. included hardware brings it to 60lbs.
I've devised a stud and retainer system to keep it from moving laterally or vertically without placing any stress or abrasion on the containers. I can also access my storage area to get to my wiring distribution point unobstructed.
The studs are 1/2" bolts, misc. nuts, connectors and 50mm urethane skateboard wheels. These easily hold a single Waterbrick without vertical hold downs if need be. The skateboard wheels are placed vertically to center inside the tapered cone shaped holes in the Waterbricks.
The hold downs are 12" 1/2" eye bolts inside 3/4" PVC and a series of washers to form a 3" hold down on top. These hold downs are configured to tighten to the studs and stop without crushing the Waterbricks.
I still need to put my 1/4" barbed fittings and Camelbak Quick Link connectors to finish it off.
My original vision was simply a 1/2" nut welded under the platform with 14" 1/2" all thread with a 4" washer and giant wing nut. I didn't like that solution for two reasons 1) I couldn't keep the containers from sliding around and 2) I didn't like the crushing force needed to hold them down and keep them put.
I decided to just leave these in the truck all the time with the caps loose and then I can just visit any public reverse osmosis water fill station before I go out on the trail.
I may choose to carry a 3rd loose Waterbrick tied up between the tire and the drivers side for a total of 10.5gal!
