Warwick xl lack of insulation

Well guess what? Mines the same, no insulation or vapour barrier and poking a cheap usb endoscope shows nothing further along either.
Really p#[You must be registered and logged in to see this link.] poor workmanship. Were Autosleepers always like this.

Loosely filling voids with insulation is important but more important in my opinion is a continuous vapour barrier.
. Unless the van lets in water from the outside then any moisture is coming from condensation created inside the van.
Items like these should be sat in a plastic cover inside of the vapour barrier like door speakers etc.

In the construction of these vans, I imagine insulation is probably the cheapest component, the man-minutes to fit it can't cost that much either,  so i'm really surprised to see the lack of the stuff, even if the 'experts' say it isn't needed.
 I think the 'wow' factor upon the owner seeing it ( or not ) will be enough to broadcast it around, especially nowadays with all the instant insargram/farcebook sites that everyone can see.  It may be all it takes for prospective buyers to look elsewhere.

If you are not going to insulate an area of the single skinned  roof amounting to over 3 square feet then a continuous vapour barrier should be in place over the whole interior stopping moisture from access to that freezing void as you say SallyB. Just the act of breathing overnight in the van deposits large amounts of water vapour which will readily condense out on the uninsulated  freezing cold  steel roof. Unless you remove the whole interior and start again however we have no chance of doing that! Do not misunderstand me however , this 2017 van has more insulation than our previous 2014 one which had a token flick of insulation here and there. There may even be large variations as to who applied it on the day, who knows?
      I suppose manufacturers have an interest too. Build the van, put a relatively short warranty on it and as we have seen failure of things such as expensive delicate control panel electronics damaged by damp means that a valuable income is gained from repairing these issues at customers expense.
