In the process of evaluating those appliances, I learned how to work the ovens and furnace pilots... so now I had extra stuff! Maybe there will be other useful parts from the truck camper, but I should be able to recover my expenses by selling the appliances I don't need, right?
The four-burner stove / oven, which has a matching fume hood...
The old Hydro Flame furnace, which looks virtually identical to my original, but a little newer... I've since learned that this model of furnace was popular because of the exterior fresh air and exhaust venting, as well as the lack of a blower fan... quieter.
I left these installed in my camper so I could readily demonstrate they were working. When I sell them, I'll just swap in my originals. Good idea, right?
Then there is the 3-way Dometic refridgerator... I plugged it in at my buddy's shop, and it works great!
