Dick,
With my 06 PT if the ign is on the awning, slides, tv and a few other things will not function. Last year I had a problem with mine coming out just by itself, found a problem with a solder connection on the board, re-soldered and good to go. Before I found and fixed the problem I would turn off the breaker at the 120 panel just to be on the safe side.
I have actually seen some poor devil cleaning up the mess after his awning came out while driving down the hwy,,,,not real pretty, guess he didn't notice it until the contact with a power pole.
