Enjoy seasonal camping! It's a good way to get a lot of hassle-free use out of your camper.
Ditto on leaving on the electric and propane. We bring our awning in, turn off the water heater and completely unhook the water. You never know when the spigot could magically open while you're away. Our black tank only contains liquids, so most times that gets emptied too. We take out all garbages, close the blinds and adjust the thermostat enough to keep it from getting to oven temp during the week. Slides have stayed open from April to October for years with no issues.
Have a terrific season!
