We have stopped for overnights on many occasions. Usually, either a Good Sam or a KOA campground. So we always have power and somewhat level campsites for the night. I still attempt to level my camper as much as possible using my tongue jack and just let it lift the truck end some. I then go ahead and put the stabilizer jacks down. My dealer told us when we purchased our camper it is always best to have the jacks down before extending the slides. So, we always put the jacks down, wherever we are at, if the slides are extended. This is just how we do it. If we do not extend the slides, we do not worry about the jacks at all. We have parked over night and never pulled the slides out. Considering we always have electricity, I always unplug the trailer pig-tail from the truck. If the trailer is hitched for any length of time, even with no electric hook-ups, I still unplug from the truck.
