Having recently done a lot of research regarding a night heater for my Vw T4 campervan, I decided on 1 of the top two brands on the market...E or W. I narrowed my choice to two companies, a Lincoln based one and Mellor. After ringing Mellor and explaining my requirements I was guided towards a webasto kit and a stainless steel exterior mount box. The advice given over the phone, even though it was only 10 minutes to shop closing time,was invaluable. There are so many kits and variables on the market I really appreciated the friendly and informed guidance. My heater kit was delivered very promptly and was very well packaged. Top marks from me!
