I had the van out for the first time this weekend without hook-up. Bit of a disaster really. It took me several phone calls and a number of very cold hours to get the dealer who sold me this new van about 3 weeks ago to advise me on how to get the heating working on gas. It did eventually work and I assumed the problem (on the advice of the dealer) was an air lock preventing the gas getting through. However, late this afternoon, when I went to switch the heating on, it again refused to work. Countless attempts yielded nothing. It would appear the problem is more serious. I had to cut my weekend short as the weather was so cold where I was that a night without heating was unthinkable. Has anyone else had similar problems? Why should this happen with a new van? Why are motorhomes so frustrating?
