First jeep purchased 60 days ago. I immediately took it to Ouray to do some camping and trails with my wife and 6 year old. The back was completely full as well as the two remaining back seats. I'm leaving for my next trip one week from today. The goal is to pack everything in the back cargo area. I'd love custom shelfs etc, but don't have the time to do that in one week. What does everyone else us for rear storage? I'm looking to at least replace the black box with yellow lid with a few less tall containers that I can stack as well as any other shelving I can buy and easily install in the next week or so.
