Running the electric heater for primary heating is pretty inefficient, I installed a gasoline Webasto heater. It really puts out allot of heat compared to my electric options.

Thanks for reply. We just got a 2002 Roadtrek 190 which does have a forced air heater but will probably augment with an Olympic Wave 3. This is probably overkill. Do have the requisite propane and CO warners. Will google the Webasto.
