We have dishes, pots and pans, towels, sheets, blankets, etc. that were purchased specifically for the RV. They stay in the RV. When we close down for the winter, the fabric items are washed, dried and then packed away into the plastic vacuum bags, placed back in the RV and are ready to use when spring rolls around. The pots and pans as well as the dishes and silverware are put into the cabinet and left there - I will wash in the spring.
We have "camper clothes" that stay in the RV year-round. They are jeans with paint spots, T-shirts that are just this side of being rags, underwear that has seen much better days, socks that are holey or discolored, hoodies that are not really fit to be worn anywhere else other than around a campfire. They, too, get washed, dried and put into vacuum bags for the winter.
Our food stuffs are brought in at the end of the season and used in the S&B during the winter. In the spring, I will purchase our staples (flour, oil, spices, etc.) and re-stock the RV.
