Virtually any cheap battery operated stat will work. In an RV the stat must have its own power because the furnace does not power the stat as in a house.
The stat simply acts as an off/on switch for the power supply into the furnace.
Ours has the 12v wires to the thermostat always live. No batteries in the thermostat. Same thing in the 5er but that one also ran the air conditioner so it has more wires and such. This one is just for the furnace. The furnace fan runs first and last with the burner switch. I don't need a fan-only control for cooling where we camp, just a straight furnace control set-up.
