It's official-- the boondocker's new cot and underbed storage system worked GREAT. Plenty of room for the portapotti, so no need to step out in rain, snow, cold-- or bad neighborhoods-- overnight.
Room for a dog, too, if I can find one.
Room as well to sit on the bed, and the plastic-drawers dresser I added for groceries was great-- next time, a tiny folding table to eat from or make a sandwich upon.
