Here are two shameful scars from my life:
I learned the easy way....by scaring myself silly after leaving a front latch closed. I popped just the rear of the roof to let my friend see the inside of the camper when we first got it. Had made the mistake of having him undo the latches on one side while I did the other side, and I didn't explain it clearly. He got the side latch but not the front one. When I popped the rear of the roof it was harder than normal, but it went up. Showed him the interior, then we closed the camper down. About an hour later my brain was trying to tell me something was wrong. I thought about it and guessed what had happened. I knew that it couldn't have been the middle latch because the roof didn't bend, but I thought for sure damage had been done. I went and checked and there was absolutely no problem. The side effect is persistent closed-latch paranoia, which is a good thing.
I also developed persistent open-latch paranoia after driving 10 miles up the freeway at 70 mph doing the worst possible aerodynamics test. As I did my neurotic mental checklist while flying up the freeway, that same feeling of doom returned. I realized I did not remember closing the front latches before leaving. Choking back adrenaline, I asked my wife to look up from the passenger seat. Sure enough, the front of the lid had popped up, and we were just entering about a 3 mile stretch with no safe shoulder or off ramps. I slowed it to 50 and did the limp of shame. A good Samaritan hauling a horse trailer pulled up in the fast lane and pointed up. I gave her a thankful thumbs up as I shrank into my seat. Luckily the next turnout was huge so I could hide on the outskirts as I closed the roof. Of course I did my best to make it look like everything was normal as I did this. Again, no damage.
