Yes, the totes under the camper is a wonderful idea - I had forgotten about that. We had 5 totes (there were only 2 of us) 1.his clothes, 2.my clothes, 3.kitchen/food 4.towels and personal hygiene stuff and 5.camping equipment (lanterns, mosquito spray, sunscreen, etc.) They were labelled with what went in them. When we packed up, we would put all the clean clothes in his and dirty in mine. The dirty towels also went in with the dirty. Those were the only tubs we took into the house - the rest stayed in the camper for the next trip.
I also purchased a plastic shelf system that I sat on the counter and it held our food supplies for the week and our TV. DH HAD to have one.
