I leave as much in pop up as possible.  Food, clothes, sheets, towels  into house.  Everything else stays in, unless I have a need for it for another function/activity.  Sometimes lawn chairs are used for picnics and gatherings, so they are in an easy to access spot.  If the screen room is wet, then it comes out to hang in garage and get dry before repacking it. 

Now at the end of the season ALL food, ALL bedding comes out, all paper(plates, napkins, paper towels).  I leave as little mouse/rodent food and bedding in as possible.  Remove all cansbottles that would be affected by freezing temps. Also cleanall surfaces  and inside all cupboards and drawers , then add bounce dryer sheets and pack it all away till spring.  Last item is a bucket or 2 with damp rid containers standing in them.

I keep rain gear, tools and cooking stuff in. We Camp year round so I also have a supply of spices,oils and packets of spice that I switch out when needed. I always have a sleeping bag and pillow in but like to Glamp with sheets,Comforter. Always ready to go! 8)
