I needed a place to mount my powertank. Things are getting tight inside my Cherokee, Much tighter than originally thought. I found a place behind the passenger seat that kept the powertank elevated above the floor to prevent it from rattling around and allow ease of use from the mounted position.
So we mounted it to 3/16" steel plate and welded it to the horizontal "B" pillar tube. Used 1" stock to connect it to the lower tubing and drilled holes in the same pattern as the Powertank mount.
