Does anyone know if you can leave a RV parked in this pkg. lot over night if it is not occupied or slept in? We may be camping for 4 days in the valley, then pull the trailer home, and 3 days later my sister would go back up there pulling the same trailer and camp for 4 days. Trying not to have to tow the trailer back home, and then have it towed back up there 3 days later. I've seen RV's parked there before for more than a day.
