2 things. I'm not sure I understand correctly. Do you or do you not have a good 12V battery on the trailer? If you do not, how did you get the trailer to your in-laws? It's illegal to tow a trailer without a battery. The battery supplies power to the emergency brakes on the trailer.
Lack of battery could be the problem, however, most likely the problem is the sail switch. The furnace fan comes on first. It pushes cold air across the heater flues. It then goes across a switch reacts to the air. If there is air, the switch allows the furnace to cut on and supply heated air. If the sail switch doesn't detect air, it will shut down the furnace.

i am very new to the RV world. I have a 2015 starcraft ar-one that I just bought used. I got the RV winterized last friday and on saturday went up to the in-laws for a big party they throw every year. i was only planning on using the furnace to stay warm through the night. we used a converter to hook the 30v up to a normal outlet (15v). The heat worked great for most of the night and then shut off. When attempting to turn thermostat off and back on again. the fan starts to run, but shoots out cold air for about 30 seconds to a minute then shuts off. propane tank is full. i tested the burners on the stove and they seem to be working fine. the flames are blue with an occaional yellow flair. i also tried at home where i have a 30v plug. It looks as if the former owner replaced the propane regulator once or maybe moved it. Any ideas on how to fix it. could it be something with the winterizing? since it is a hydro flame...
