Pots and pans, kitchen utensils, linens and bedding, a couple lawn chairs, etc. All stuff that was surplus household goods at the 40 year point in our life together, i.e. very little bought "for the RV."
No foods or other perishables. Most of the camping equipment comes out because I use it also picnicing and tent camping. Tools come out, get used at home, put in other vehicles for non-RV road trips.
If you are snowbirding or full timing, answers are different. Full timing, by strict definition, everything you own is always with you in the RV.
