Does the stove and fridge work ok? I know you also have a propane connection in the passenger outside compartment. It work ok too?
Determining whether the problem is related to a specific piece of equipment rather than all propane related equipment is important.
If just the furnace, it could be a number of things like air or moisture in the line, or something gumming up the orifice, or not sensing the flame or the ignition board is defective or a bad ground or possibly the flame rod is dirty, etc.
If it is affecting all equipment, it may be more related to the propane. Keeping the tank warm can help in some situations.....(the following borrowed from another site)
LP Gas Pressure
A furnace is a consumer's friend when the outside temperature gets colder. Unfortunately though, cold is an enemy of LP gas. The BTU capacity of LP per volume decreases as the outside temperature gets colder. Therefore, based on how full the LP tanks are, the ambient temperature outside and how many BTU's the furnace is, there may not be enough gas to sustain ignition on the furnace. Using the charts below, let's say that a 40,000 BTU furnace won't fire up, and we also know that the 65 lb. LP bottle on the RV is 40% full and it is 0 degrees F. outside. One's first thought might be that the burner or valve is bad. However, if we use the chart, the vaporization capacity of the tank in these conditions is only 38,500 BTU's. The furnace is not going to perform very well because there is insufficient BTU capacity in the tank. If you were to put an insulated fire resistant blanket over the tanks and a 75 watt light bulb under that, you would probably raise the temperature of the bottles 10-20 degrees and almost double the BTU capacity of the tank. This in turn would allow the furnace to operate properly. So keep in mind that a furnace problem is not always a component problem.

Luckily, I don't think that the time or cost of having a tech look at it will be very much at all. They are fairly simple pieces of equipment.
I was advised to take a look at Trailer Life's RV Repair and Maintenance Manual by Bob Livingston (4th edition). I did and eventually bought a copy, even though it has been out of print for years (got it on eBay). Lots of great info for problems like this, but trying to describe the entire troubleshooting process is a bit difficult here.
Only other advise I could give would be....head south not north!
