After a camping trip we put up the camper in the driveway and clean everything, floor, fridge, cook top, toilet/ shower, everything. drain the lines and the water heater after each trip.
We restock the paper goods, and anything else we used up.
We make sure it is completely dry before dropping the top, and we are good to go for next trip weather it's in a week or a month.
Before we leave for a trip all I have to do is check the outside stuff. The tire pressure including the spare, the battery and the propane and pack food and clothes and linens.
You have a good amount of space at the door with the top down, we fit our cooler, and linens in it no problem. Just lift the top about 2 inches so you don't damage the seal on the top of the door and you can access it with the top almost completely down.
By splitting things up you keep thing clean and maintained and have half as much to do before going. The important stuff is done right after the trip while it's fresh in our minds and nothing gets put away dirty or wet, the two big enemies of the camper.
Hope it helps, happy camping
