End-Mount Slip-On Units generally have a lower center of gravity than Top-Mount Units. The controls, pump, plumbing and sometimes reel are mounted on a platform at the rear of the water tank. The tank and rear platform are supported by a frame that is constructed from a 2” tubular aluminum and welded into a high-strength, non-corrosive unit. The tank platform is covered by a .125” aluminum diamond plate with a 1” return on top, 3” return on bottom platform, and welded corners.

End-Mounts are great for trucks with utility boxes or flatbeds. We can also build custom boxes to fit your Slip-On package.

Larger sizes and custom options are also available.
