You have an 8531-111 or some such? Ok you obviously have a short in the 12v somewhere. It showed up after the motor ran the fan but then it happened. The sequence for ignition goes through a number of things so need to pin down where it stopped.
You said there was gas but no ignition, and then it shorted again? Please confirm you smelt gas. If you did that means the 12v got that far, but if you didn't really smell gas then the fault could be earlier in the sequence.
no, smelled electrical smell. Never smelled gas.
In the OP you said the furnace guy had the gas turn on. Please clarify. I understand the electric smell was the burnt out thermostat.
Anyway somewhere, one of the positive wires is touching RV frame ground which blew the fuse panel fuse. The furnace 12v is grounded to the RV frame. The thermostat just connects and disconnects a positive wire.
Bunch of wires on blade terminals to the various switches--maybe one came off a blade and is touching metal. The motor ran the fan so it must be after that when the sail switch closed and made the next or so positive wire live, and it is shorted. (My theory--not to be confused with actual knowledge :( )
