Heat Pump or Not

Doug, again thank you. I like to know how things work and why they are designed the way they are. This information is priceless. I had not been able to find anything this thorough and clear to understand during my research. After a career in the Air Force and just the business of life, we are just now getting to the place where we can start to use our RV. It's older, so there have been a few kinks to work out. This information is very helpful. You should write a book (if you haven't already). I'm new to the forum, but I will try to figure out how to follow your posts specifically. Thanks again.
