The joys (or otherwise) of life in a campervan

There are always "issues" with life in a campervan, motorhome, caravan or recreation vehicle. Over the few years that I've been travelling I've had a variety of problems with either my first slide-on campervan or my second van, or incidents have happened that may or may not be funny when I look back on them, but were definitely not funny at the time.

• The van's in the air ready to load onto the truck. Why won't the truck start?
• Always remember to close the fridge door properly...
• What do you do when the front door key won't open the door?
• What's that red liquid pouring out of the van?
• Is it supposed to be raining inside the van?
• Water is leaking into the van. Every time I fix the leak, another one appears.
