Hi Frank hope all is going well with your conversion. I converted a LWB Ford Transit a few years ago and it came out pretty good. I used 12mm veneered board for all the furniture, a bit on the heavy side but it came up good. Behind the drivers seat I put a small wardrobe with a porta potti at the bottom. The beds were across the back which I later changed to one across the back and one along the side. The van was lined with 3mm board behind which was some pink batts I had knocking about. I put in the 240v cable and an electrician wired up the plugs etc. and then gave me a certificate to say all was in order.For cooking I only had a portable gas cooker ($18 touch) inside as the regulations mean that you ahve to have a gas fitter to do the work and a sealed box for the cylinder. When I had finished I made an appointment with Vic Roads at a country office to get the rego changed to motorcaravan and they did not even come out to inspect the van...probably because it was raining.I found that all the info you need can be downloaded from either Vic Roads or the CMCA
Good luck with your project Keith
