Thanks for the information. Not being a HVAC expert, I wasn't aware of that.
It's now a week from Thanksgiving and I'm still doing well in the shell. Got back into RC models (I fly micro helis in my space). I found a good church home here in Willis and I'm meeting some great people.
My camping accommodations are about to change. A heavy wind destroyed my awning so I was back to square one. Then it occurred to me that I have a 6x12 enclosed utility trailer that would make a good camper. Long story short, the park owner gave me the green light to bring it in. My neighbor 2 spaces down power washes RVs and reseals RV roofs. He referred me to his brother-in-law who is a carpenter. They are redoing the inside of my trailer and I'm going to repurpose it as a camper. My neighbor resealed the roof already as a couple of leaks were discovered in some recent heavy rains. It should be done next week. I'm having a shelf run across the front wall which will do kitchen duty as well as holding the TV. I also ordered a simple twin bed frame and memory foam mattress. I'm doing a rustic finish inside. My truck will then be the storage unit but can continue to be used as a camper. With all the time I've spent in it, I've gotten the truck camper really dialed in and is very comfortable.
