Fella has had our van for 6 months to do conversion !!!!! Is a Ford, Transit Jumbo. Originally said he cld do a decent conversion for 8000, however, has now said he can't even finish it for 10 properly. Really disappointed, don't think he's ripping us off as is good bloke and maybe underestimated size of job. However, he recommended a diesel heating system originally, meeting up with tank, he's now said that will cost £1300 to do and we're better off leaving that out for now. Does anyone have any idea if a propane heating system will be a lot less ? We had a blow propane system in the last campervan.
