Donna, we agree getting locked inside our egg is a creepy thing. We experienced this on the return trip from picking up our
Scamp in MO. We took refuge inside the trailer to
escape the mosquitos, and when we went to exit - oops, locked! Never did quite know how it happened ... the worn & rotating cylinder sounds plausible.
Anyway, I'm pleased to say you can rescue yourself if you have the larger window which slides up/down. The screen is easily removed; we had one set of keys on a long lanyard so just reached out and unlocked that door (HUGE sigh of relief here). Hope this might help other
Scamp owners if ever in this predicament. Take care, L 'n D
