I have a Girard tankless in my camper.. Used it for a couple of years now.. don't hate it.. but almost. I have learned to use it, but it's a pain in the a$$. Too hot or too cold. I have read all the directions.. called Girard and tried all their suggestions. It still sucks. You shouldn't have to jump through so many hoops.. just to take a nice shower.
As mentioned.. I have learned to use it well enough to take showers. I mostly always camp by myself, so no big deal. But I would never let a child take a shower in my camper... they would probably scald themselves.
Been thinking about replacing it with a regular gas/electric tanked water heater.. but since its only me.. I'll probably just save my money and live with it.
My opinion: If you have the choice upfront.. stay away from a tankless water heater.
