Hi dutchie01,
Can you provide some additional details?
1. Does the fan run?
2. Is the thermostat display working?
3. Is the thermostat calling for heat?
4. Do you get a good and consistent flame at the stove?

thanks,

Running the stove to get the propane lines filled sometimes helps on reducing the heater cycling modes (prior to starting) if furnace was sitting for a long time. This can also help to determin LP flow if the tank is low and very cold; its ability to deliver may be diminshed. Just trying to keep it simple. Just expanding on what GaryKD already asked.

thermostat set to furnace temp set to 80 turn on and wait nothing happens no fan no flame nothing, no propane smell stove and water heater both work and tank is full

The fan needs to run and move the "sail" switch in order for propane to flow.
I had this problem with a trailer I had. The control board was replaced to fix the issue.

Depending on how "techie" you are, if you find the wire connections where the thermostat wires connect to the furnace, you can either check for continuity of the wires coming from the thermostat or even simpler, just short across the thermostat wires. If the furnace fires up, your problem is with the thermostat. Not knowing what kind of heating/cooling system you have in your unit, this could be an easy fix with a thermostat replacement or could be more serious. Anyway, that's a place to start. If you're not comfortable with checking the thermostat as explained above, have an RV tech check it out.

If your furnace has not been on for a while you will have to remove the air in line feeding the furnace. Closes to furnace is your stove, it may take a few firings of furnace to clear remaining air in line.
Here is a PFD of furnace operation.
If you do not hear spark for igniter it may need to be cleaned maybe dirt or rust in spark gap probe.
Make sure you have 12V feeding the control board.
Check the wire clip connections for clean connections also may have corrosion.
