It can be the campground electrical. There was a campground I worked at that had 3 sections wired seperately. The oldest section could not support all the rv's running everything, especially all the AC's when it got hot. One weekend while working the power would go out (main box just about burning up) wait a bit, turn it on and everyone's AC's kicked on at about the same time - that would trip it again. Could not get them to understand that everything coming on at once was also contributing to the problem. We are talking an area with about 50 rv's. Campground and county admin knew about the problem, but planned on redoing that whole section within 2 years so were doing nothing about the electric. Only happened when they were full like on a holiday weekend. What a pain as the campers took their anger and frustration out on us workers. We couldn't do anything about it. Stuck between the powers that be and the campers.
