I have a couple of small office sized oval plastic trash cans. The driver's side has the water filter and tank filler that fits the end of the hose, as well as the bottle of poo tank enzyme we use (instead of harsh chemicals). The rolled up hoses fit nicely behind it.
The passenger side holds the tools for setting theWDH bars and the crank for the stabilizers along with a few other odds and ends like 15 amp and 50 amp adapters. The power cord fits nicely rolled up behind it.
This leaves room for my leveling blocks, Anderson leveling wedges and the immobilizers that fit between the tires.
I lay my WDH bars across the top of the plywood covering the batteries when they are not in use.
