For us, that really depends how often we are using the camper and for what we are using it for.
I suppose I should start with those items which truly stay inside the camper and never make it back into the house. Those items would include cooking utinsils, pots and pans, dinner wear, silverware, electric skillet, electric griddle, and a butcher block knife set. Then there are the tools that are unique for the camper. Specific square headed screw driver, the stabilizer crank, some specific hand tools, a small select box of screws, wire, tape, things like tent pegs, rope, hatchet, 30 amp RV extension cords of different lengths, the folding lawn chairs, Quick Shades (we have 2 of them), yard mat, outdoor lighting and such.
These are the types of items that stay with the camper permanently regardless of time or season or what's going on. If I had to bring these items in the house, I have no clue where I'd store them.
We have on occasion used the Quick Shades at different events (non-camping related) but they always go directly back into the pass-through when done.
It seems everything else will come and go, in and out of the camper, depending on what's going on.
We have the luxury of parking our camper at home, and we plug in the camper electric and have the ability to dump our holding tanks. So, especially during the Summer, we virtualy live in the camper all Summer, Spring, and Fall at home when not camping elsewhere on week-ends, 4 day week-end trips, or week long trips through the year.
So, during the "Summer" we keep everything in the camper. The refrigerator is always on, it always has frozen food, drinks, butter, everything in it. Here again, this depends on how often we actually plan on "going out". If we know we are "going out" again in the next 4-5 days, we keep everything in the refrigerator from one trip to the next. We do prepare meals in the house and when things run out, we usually run out to the camper to get them. (Like Milk, butter, etc). We keep frozen meats in the refrigerator, but often will use it up during the week, so before the next trip out, will replenish the meats. What we don't use camping out, we'll probably use at home eventually. So, we've not loosing anything by overstocking.
Laundry comes in the house after every trip, but is returned to the camper immediately after washing. However, at the end of the camping season, and we're primarily "driveway camping" all the clothing comes back in the house. Actually, my better shirts, pants, and undergarments are in the camper. So if we go some where where we have to be dressed up, we usually have to get those things out of the camper.
We basically keep the camper stocked 100% with everything all the time so we can take off at the spur of the moment. We've actually done this a couple times this year. We decided Friday morning we were going camping and Friday after work, could just hitch and go! Everything was ready.
Now, winter is a different matter. Pretty much all clothing and all food and all liquids come back to the house. Laundry is done, including bedding, but bedding is put back into the camper. Everything else stays.
Since we driveway camp in the winter, the refrigerator is never turned off. But we've learned not to keep any liquids in the refrigerator unless we are actually in the camper. We don't heat it all the time, and sometimes it will get way below freezing inside the camper. Things in the refrigerator will freeze too. But we spend almost every week-end in the camper in the drive way, even in the coldest winter months. We really enjoy sleeping in the camper. In the winger, there is never any food, unless its chis or drinks which are consumed immediately.
So, basically, for us, everything stays in the camper unless we've had to rob something because we ran short in the house.
