I pack and unpack, because outside storage is just too hot for much of the year to leave behind anything heat sensitive or perishable. I work with the checklists my late wife developed for her inside part of it, but I don't take so much that it is any more than a 30 minute job, or more than 5-6 trips from the house to RV. The packing is a lot less work than the pre-trip mechanical inspection, water system sanitizing and flushing, which is a few hours spread over one or two days.
One thing that has helped has been keeping the checklist handy, so that I can note what did not get used, and what I needed that I failed to bring. Enough of this refinement, you'll find that you are packing a lot less stuff than you formerly packed.
