Hi Tonya,
On the furnace, yes the propane needs to be on and enough in the tank to run the furnace. If you can light the stove top burners after all the air is out of the lines, then there is enough gas to at least start the furnace. How long it will run after that depends on how much is in the tank.
Your newer 2001 Sunline will have electronic ignition and will light themselves, no pilot light. Assuming there is gas to the furnace, the camper battery is charged enough to run the fan fast enough, (or plugged into shore power) the Thermostat is calling for heat and there is nothing not broke on the furnace, it should light the burner itself.
If you light the stove burners on gas, then you can shut it off and then try the furnace. If everything is working on the furnace, it should light. If it does not, then we need some more info to help dig deeper into this.
We need the model of the furnace as a starter. It should be in the manual if you have one. If you do not have a manual, the model number is outside the camper behind the screwed on cover. Take the cover off and the sticker is there. A picture with the cover off helps too. Also, when was the last time the furnace ever worked?
Here is a real quick troubleshooting thing you can do and report back with the model number if you need more help.
Start the furnace, the blower should run after a slight delay of calling for heat. You may have this already as you said the blower runs. The blower running is a good start. No blower, that means something by itself.
About 30 seconds to maybe a few minutes after the blower comes on, you should hear a "clunk" which is the sound of the gas valve opening. Then a faint buzzing sound of the electric ignition. Listen close for it. If you never here the clunk or faint buzzing, then the gas burner never opened and tried to start the burner. You can turn the furnace off and on and try this sequence listening for the clunk a few times to make sure you hear it or not.
If no clunk at all, and no heat, then there is a problem that needs to be dug into. If you know someone who if electrically friendly with 12 VDC and has a voltmeter, and knows how to use it will be needed next.
Note: the camper battery has to be charged full enough to run the fan fast enough for the furnace to meet the safeties and open the gas valve. Make sure the battery is good and turned on. If you can plug in the camper to shower power (120 Volts AC) , your vintage camper should make the power needed to run the furnace too if the battery is low.
Hope this helps
John
