In reply to abr1966:
I got my Dispatch to stealth camper for £61.
£50 for self adhesive insulation. Its peeled a bit on the roof, should have got the equivalent silvered foil for about £10 and used my own glue.
I have access to lots of timber buck shee, so allow £50 to £200.
Also had mattress , cushions so allow £ for that., check out futon mattresses .
The other £11 was for a wass set up so she did not let the midges in overnight, but I am not supposed to advertise that
