Preparing for a hot summer – campervan ventilation

Summer is officially here, and the temperature has soared over the last few weeks (sorry to anyone shivering in the Northern Hemisphere). All through winter I was wondering if we’d have enough cupboard space to store a 25 tog arctic duvet during the day (answer: not a chance), and suddenly it’s a question of how we’ll be able to cool the van down, particularly at night.

The front of the van has air conditioning, but it only works when the engine’s running. So as extra ventilation, we have the ceiling fan which provides a good breeze, and even when it’s not switched on, the open vent lets some fresh air in. We also have an air vent in the door next to where we’ll sleep:

To fit a vent:

  • Draw an outline of your vent panel on the inside and outside of the van.
  • On the outside of the van, cut three 10cm diameter holes through the body work with a hole saw, and seal them with a rust proofer. Note – if you’re fitting a vent to a door like we were, you’ll find it has extra bracing and reinforcements than the rest of the van – be careful to avoid these when you’re drilling.
  • Drill 6 bolt holes around your outline on the outside and rust proof each one.
  • Squeeze a line of silicon around the inside edge of the vent panel intended for the outside of the van (to prevent water seepage).
  • Attach this vent panel to the outside and bolt through.
  • On the inside of the van (ours is hard board) cut a square hole a few centimetres smaller than the outline you’ve drawn, and tighten the bolts you’ve just screwed through with nuts. Take care not to screw them too tightly, as the outside body work will start to bend inwards.
  • Fit the inside panel over the template you drew and simply screw 6 bolts into the hard board.

We have two other vents in the van: in the battery compartment and next to the fridge. The fridge didn’t strictly need one, but it’s an added safety feature in case it ever overheats. These two vents were much more straightforward to fit; they’re not visible from the inside so the open hole can be exposed, meaning you only need to bolt a vent cover to the outside. Here’s the battery vent from the inside:

We also have an extractor fan above the gas stove:

So that’s the campervan’s ventilation, but hopefully for most of the time we’ll be sitting outside under our lovely new awning!

For some reason awnings are incredibly expensive. This one is a Fiamma ‘bag awning’ from Caravans Plus and a really basic version, but it was still one of our most expensive campervan purchases. You have to roll it down manually, but it seems to work okay.

The frame is fixed to the van and you roll the awning in and out of its bag. You can then remove the cover and store the whole thing inside when you’re not using it.

So there’s not much left to do now: refit the ceiling, build a bathroom door, fit the door handles and then we’re almost there! Oh, and make 11 curtains.
