I have been looking at both the Flip Pac and the FWC, as I recently sold my rig, and going to build up a new adventure truck. Kinda leaning towards the FWC, since I do backcountry skiing. I found a wrecked late model Tacoma. The rear has been smashed, perfect candidate for a flat bed/camper. Flat bed would have tool boxes with either a FWC, or a Flip Pac bolted to the top of the tool boxes.
Thinking of doing a small collapsible table that hinges to the side of the inner camper wall, keep it folded up whole hauling gear. Deployed while in camp mode. I do currently have two 24X48" portable tables that work great for cooking on outside the vehicle. Small enough to fit across the front of the bed of the truck, they take up very little room when stowed. I bought them at ACE.
