can't keep pilot lit
I am not particularly adept at such problems, but there are three possible causes that I am aware of. The first being an obstruction in the exterior furnace exhause vent - - mud daubers, wasps and spiders seem to love to build their nests in this device causing all types of trouble when the furnace is needed. The second possibility is a problem with rust out in the heat exchanger allowing wind to blow the pilot out - - this is a potentially deadly problem as it means there is a carbon monoxide leak. The last problem that might cause such problems is either a thermocouple or sail switch that has failed or is failing. This is an area that I always turn over to a trusted RV LP Gas technician as it is a life-safety issue.
Good luck locating the problem.
