We have a DP and as far as leaving a site, we start the engine and then disconnect water, sewer, and electric, usually in the time that takes we come up on the air enough to bring in the slides. We bring in the slides which takes another couple minutes and idle out. It does take almost 10 minutes in all. We can't move our slides until we are fully up on the air. As far as pulling in, we turn off the engine to extend the slides but then need to start it again to level, but that only takes a minute unless very unlevel site. Idling into the campground cools the engine enough to shut down.
