once after leaving a campground, DW said "what is flapping outside my window?"
I'd forgotten to put the door awning in...
We pulled off in a handy parking lot. I hit the switch and nothing happens... I look and wiggle and prod. nothing. I don't have a ladder so I unhooked the jeep and pulled it next to the coach so I could climb up and reach the awning. All looks normal. I need the toolbox so I can start taking stuff apart, but that compartment is locked... hmm keys are in the ignition (motor is still running...)
So I move the jeep, get the keys (shutting down the diesel...) open the compartment, get the toolbox out...
And just for fun give the retract switch one last try... WHIIRRR in goes the awning.
They interlocked it to the ignition switch!
