Last year upon returning from my hunting trip I was driving in a lot of slushy snow. I usually take the camper off the truck to store for the winter and this particular time I stopped by the self serve, wand-operated car wash... I did not want to have it all dirty while sitting all winter.
Even though I did not spray water directly at/on the door and access hatch locks, they nonetheless got water in them and froze to the point where I could not get a key in to continue my unloading when at home. Not a big deal as I got the heat gun out and defrosted them.
In the future, I might just keep a rag and roll of duct tape in the cab to wipe and then put a small piece over each door cylinder (all 4 of them) when washing the camper in cold temperatures to make this little chore easier when in similar conditions.
