We have items just for camper (Sheets, pots, pans, etc..) we try to keep everything needed in camper at all times. Pretty much we pack a duffle bag with clothes, bring fire wood, Pack the camper only cooler with food and fridge. We don't really pack much because it is already in camper. we wash sheets, blankets and linens when we arrive home then put them in a vacuum space saver bag and put back in camper. The vacuum space saver bags are great for the camper
We also buy camper things off season (the space saver pots and pans that nest together, the 3 in one utensils etc..) They make so many things for camping that take up little to no room. (we have actually bought some of these items for the house kitchen. Shop at camping world type store but buy at Walmart or amazon
for cheap. Keep it simple. Yes these items cost a little money but time is money and camp in the driveway a few times and use the $$ saved to buy camper goodies
Most of all when you have everything in camper...you don't for get it at home!!
