I know from experience even strapped down tight the cans do expand quite a bit and pressurize out in the heat,You need to make sure those jugs are absolutely positively 100% leak proof while being heated excessively and shaking and banging around. Lots of off road rigs have burned because of leaking gasoline jugs.
Hey Jenny,I have actually tried two things using a arctic cat mounting system from Country Cat for rotopax cans. The first photo mounted on roll bar cross member the second photo mounted on roll bar. You can see the mounting system in second photo. Also I have one on each side. Had to cut a notch on the one I mounted to accommodate the seat belt mount. The third photo I added a little mini rack between the two mounts.
