I forgot to mention-- that we only do this when on the road and get tired. In the morning we head on out on our way. Sometimes we start the generator to run the microwave, or cool the trailer down or whatever, but I have it mounted on the back of the trailer and it's the type that are "whisper" quiet. Whatever the case maybe it doesn't stay on long. Sometimes I'll put the jacks down. I have a cordless drill that lowers them in seconds. It all depends though.
Safety: We've never had a problem-- if someone wanted in, they'd have to get through my two boxers, then they'd be told to smile and wait for the flash-- of my 1911.
The key is subtle stealth'ness, and using your noodle.
sorry about the typos and that run-on sentence, I forgot the period up there.
