I noticed this past weekend on the douglas run, that one vehicle had Molle panel on the inside of the rear door. I have been of a mind to by surplus molle panels from ebay that we made to fit military hummers front seat backs. About $20. Any military pouches or after market copies will all fit. Pouches and panels can be purchased from Ebay, amazon and any surplus outlets. I can think of almost infinite uses from first aid kits, fire kits, tool sets, etc etc. Pouches could be attached with molle webbing or velcro panels for quick grab n go uses. I think they would be a great way to organize your overland rig and put commonly used items close to hand when your on the road.
Please chime in and tell us what YOU would put them to use for, or what you may use them for.
