Is the RV unit plugged into 110 volt shore power or just on battery? Furnace needs 12 V DC to control board. It will operate down to 9.5 volts but not any lower. From what you are describing it sound like the furnace is having intermittent prof of ignition problem. When the pilot in the furnace lite's with the spark ignition the pilot flame is in contact with a flame rod the control board passes a small DC current though the flame to prove the pilot gas is burning. If it dose not see the DC current in less than 5 sec. it will shut the gas off and shut the fan down. after 30 sec. it will try to lite again and will do this 3 times and lock out the furnace if it dose not light. The only way to reset the furnace if this happens is to turn the heat off at the thermostat to cycle the 12 V DC power to start the furnace. In short it sound like you have a pilot ignition problem. If you don't have a good working knowledge of propane don't play with it. If the dealer you have can't fix it take it to an other dealer or call Suburban for a dealer near you that is a factory rep.
