Atwood-Hydro Flame Furnace Thermostat Replacement

That's my rig! We love the layout and the large restroom across the back is the best feature.
I actually got the original documentation and manuals with all the appliance spec sheets.
The original owner, a friend of mine, kept the manual from the dealer with tabs for each appliance.
I'm just trying to familiarize myself with everything.
I upgraded the converter, added a new battery, new tires, new matteress and new vent covers.
Washed and waxed it and it looks like brand new!!!
