RV Repair: 2001 Skyline Nomad Furnace Issue, propane tanks, pilot light

Question
Pilot light goes on to ignite furnace flame and then goes out in a couple seconds. Any help would be appreciated.

Answer
Sounds like your not getting propane.  This is caused by a few different things.  Most often the regulator is plugged at the propane tanks.  See if the stove will light.  Second reason could be bad ventilation.  Make sure the furnace burner can breathe.  No rugs, clothes, plugging up the vents.  Is the gas valve working?  Are you low on propane?  Is it possible the propane lines are frozen?
