The one with the hookup lid is really annoying ;-) did that a couple of times this summer …
Almost forgot to lower the mattress BEFORE lowering the roof …
The fridge thing. But only once …
Almost rolling down the ramps, withe the awning still out …
My worst nightmare is to drive of without removing the cable. Never did it, always go a round before driving away after hookup for the same reason.
To loose the key on a remote camping …
This one is funny. On our first wild camping, we had some wine and went to bed upstairs. My wife woke me after a short sleep, totally in stress – fighting a lot of mosquitoes – they were everywhere! And it seemed they where increasing in number. After a while I had a look downstairs and well, then replied to my wife: "Honey, maybe you should close the tailgate …" (she went to bed as the last one). We had a great laugh about that, and the mosquitoes just rushed into the van as she turned on the light to fight the few.
