I am wanting to mount fuel cans on the sides of my jeep. I want to mount one on each side between the front wheel well and the doors. I currently have two one gal military cans that I want to use but I also want to be able to change out cans or attach other items (ammo cans, etc.) I mean this is just wasted space. Any ideas how to go about this, mounting points. BTW I also want to avoid any unnecessary drilling and be able to undo it back to factory if needed.
