Happy Christmas to you Phil.
I think Phil (@Admin) may have a lot of other things going on. Shame because I think WC would benefit from this site joining them
I fitted one in my garage/workshop a couple of years ago. Only change I have made is to use an old 20 ltr plastic oil container instead of the flimsy tank that comes with it. The key fob remote means I can turn it on from the house and it’s warmed up nicely when I’ve had my breakfast 😀
I had exactly the same, couple turned up and looked at the van, had a test drive and said yes. I expected lots of phone calls about how things worked but have never heard from him since he drove it away.
