Hey There! Good Luck!
Congratulations! When I first started with my old minnie winnie, I made a check list that I put on the steering wheel when I parked at the campground, with things like "slide- in and secured; propane off; antenna down; doors latched; toilet seat down; stabilizers up" - 10 years later, I still use it but now on my Jayco Greyhawk. Not to sound too ocd, I also put a dry erase sheet on the back wall for notes while I camp, things to remember and when I gave the old dog her medicine.
