Hi

I have a 2010+ Doblo MPV (not van), which I intend to use as a micro-camper with a self built 'boot jump' arrangement.

All my research emphasises the importance of insulation to minimise condensation, but all the blogs, posts etc that I can find refer to the Doblo van, and not the MPV.

As far as I can tell, the vans have unlined metal 'ceilings', whereas my MPV's ceiling is lined. I haven't investigated throughly but from what I can tell is it some kind of firm solid foam, rather than just sheet material over an air gap.

So, my questions are:

1) Is the existing ceiling sufficient insulation? (I'll not be cooking in the van, so the only source of water vapour will be breathing - though that's a lot overnight!)

2) If it's not sufficient, or an additional vapour barrier is recommended, how can I remove the ceiling with a good chance of replacing it successfully without broken clips etc? And is there space behind to fit insulation?

Thanks!

On my 2011 7 seater the headlining is 8mm thick and includes a thin layer of insulation. There is no other insulation between the headlining and the metal roof. Personally I would leave as is and focus on things like curtains to improve insulation for sleeping..
