I decided to drop the TV down off the jacks, pull in the slides, unhook from shore-power, and give it a little chance to stretch it's legs today...
Privacy shades out of the way...
Tire covers off...
Jacks up...
solar charger disconnected...
Power cord disconnected...
Slides in?
Not quite!
It turned out that I forgot to close up the bedroom windows that were in the slide. They were catching on the body of the RV, as I tried to retract!
Fortunately: I caught myself before I did any damage.
The moral of the story: don't forget about windows in your slides!
