I thought I'd share this inexpensive idea. I'm always afraid I'm going to forget to unplug the AC, turn off the propane, etc. and mess up my Clipper. At first, I was using a check off list to remind me, but it was tedious.
Then I found these: http://www.campingworld.com/shopping/item/rvminders-set-of-10/66688
I LOVE them. There are 10 tags as follows:
TV/Satellite/Antenna
Dinghy/Trailer
Slide Locks
Hookups
Jacks/Chocks
Steps/Ladder
Doors/Vents/Windows
Compartment Locks
Blank
Blank
I used labels on the ones that I didn't need, so instead of Slide Locks, I have Propane; as I now have a cutoff switch for my house battery, one blank will become Battery.
They wrap around your steering wheel and are really hard to miss. I worry much less about forgetting something before I drive off into the sunset.
Now, I just have to remember to wrap them on the steering wheel when I park... ;D
