Typically RV furnaces don't like to not be used for a long time. Too many things can happen.
1. The green ground wire that is screwed to the furnace metal gets loose or corroded. Loosen and tighten it.
2. Mud daubers build nests inside the furnace. This either clogs the blower air path, or worse builds up on the sail switch. Maybe blow some compressed air through the outlet to clear it out and hope that helps.
3. There is a control circuit board with a connector on it. Sometimes the connections on that board get corroded. Pull the connector off and on several times and see if that solves the problem.
4. Probably not the case, but also possible the gas valve is stuck.
5. The heat sensor rod may not be clean and is not sending an igniter signal to the gas valve.
I'm sure others will have additional ideas.
