Newbie First Trip Mishap

Last weekend i took my van out for its first trip. Unfortunatly it did not start well as i underestimated the length when pulling out of my driveway. subsequently i caught the back end on the wall. The damage was not too bad but the bottom hinge on the storage door at the back where the bunk beds are was bent and scratched. Although a bit stiff the door still closes and locks. My question is this during the weekend there was torrential rain and i noticed that round the seal was damp each morning and so was the sheet on the bed but no puddles formed on the floor. Is this normal ? bearing in mind we had the heater going for long periods so condensation was forming on all windows. Thankfully the rest of holiday was a great success and we had no more problems. Just really annoyed with myself for letting it happen. Lesson learnt.
