Ok thus is just for shits and giggles, eventually there will be brackets welded to the tire carrier to brace the #20 tank. The weight will always rest on the bumper and need to be removed whenever the rear is opened. But would the straps be fine? I tried standing on the bumper pulling up to see if it would slide out and that tank wouldn't budge. I would add another strap from the regulator guard down to another mounting point and ratchet it down in case of a roll-over.
Any thoughts, ideas, warnings would be greatly appreciated! Just in case your wondering the tank will only ever be mounted only on off-road excursion, with short freeway runs to the trails.
Thanks for the advice in advance!
