  1. I have this Wayska Diesel Air Heater mounted under the Air Stream/Mercedes 3500 Sprinter van. I took the time to tie it to the existing diesel tank. It’s been installed for about two years, and has been a great decision…

  2. Why did you only give the BTUs for only one heater? I am old school and don’t know how many BTUs KW is. I do know the furnace in my Class A is 35,000 BTU.
