I have the outdoor kitchen but there is still a considerable ammount of unused potential there. I have been trying to talk the wife into letting me cut an opening into it and buying a door that matches our cabinetry for it. She has been against that idea for some reason. The biggest problem is that since it is after the axles you have to be careful on the weight you put in it. From my understanding, travel trailers are very picky about weight placed after the axle (more potential for sway). I think this storage possibility would be great for extra linens, clothes, paper goods, and maybe a case or two of water but I would be careful about how much weight put in this area.
