Ditto on the laundry baskets. We bought two cheap, square-ish ones. We use them to bring down the clean clothes & linens, transfer the stuff into the cabinets, and put them under our lift-up bed. During the trip, dirty clothes just get tossed into the baskets under the bed, & when we return, they're ready for taking back up to the house. We usually wash the sheets & towels right away & take them back down in the baskets. Linens get stored in a plastic storage box under the bed (along with the now-empty baskets). We also use collapsible fabric grocery "bags" (these have stiff, square bottoms) for bringing in (& out)the foodstuffs.
Pretty much everything else is duplicated in RV & house so no significant additional unpacking needed.
