I mocked up the install on my front rack. I separated the two cans so I can strap something down in the middle and it also lets me mount them further back on the front rack obstructing the view slightly less. The second pic shows it's about an 1/8" away from the little raised crossbar. How much movement/flex is there in the rotopax gas containers? Will the rotopax rub on the cross bar as I'm bouncing down the trail?
