We managed to get camping there no problemo during the eclipse w/no reservations thanks to the trailer, something unthinkable before w/a tent.. we rolled in late at night and the only place to stay was a $500/night Shallet.. so we pulled into a boat parking lot, crawled into the camper and slept for a few hours.. when the sun came up the next morning we were waiting first in line at a campground on the other side of the park, as soon as the host station opened up they let us in and choose from any of the sites that opened up overnight.. by checkout time there was a half mile line outside the camp and most of those guys didnt get diddly... early bird gets the worm, and when you can packup your previous camp in minimal time and hit the road it helps a ton..
compared to my car camping w/a tent days, the camp grew to the point where teardown took about 45m-1h if we hauled ass this was a huge payoff investing in a trailer.. dunno how those guys stand those complicated tent trailer setups, some of those elaborate dr seuss tents look like an hour to tear down camp would be a bit optimistic.
