A question or two, maybe three on the heating system on the Berkshires and maybe the BH will differ from the RB models, not sure.
1. The furnaces have nothing to do with the a/c units above, meaning they don't even share the duct work ?
2. Speaking of duct work, are there more than 2 spots in the coach that puts out heat? I have 1 floor vent between bed and step up to rear bath. Then there must be a heat vent under the couch because we can feel heat coming out from under the front of it. Any besides them 2 areas?
3. Old fashion thermostat next to the fancy electronic one ( looks something like an old Honeywell ) what exactly does that operate? And is it totally separate from the electronic one ?
