Leaves enough room left over for some extra extension cords and a couple fold up chairs. I built it with pressure treated wood and coated it many times with Olympic wood stain and all fasteners are galvanized. Quite cheap to make including hardware, but being fussy in the details sure takes alot of time. Worth it though, I suspect it will outlast the camper
I built a wire mesh tray under the 2nd front section and between the frame rails so I can carry the blue tote, firewood, chairs, etc. it is about 60"x60"x12" and hinges down to load and up to travel totally out of the way. Lots of room and no lower that the sided of the camper. I have room for another the same size in the rear section, but have never built one there. If you park in a spot where you must put the hitch on the ground to level, make sure you unload first! This could be built as a slide-out joey-bed if you had more motivation.
