Furnace won't fire up on new TT.

[LilBigfoot]

Hello..I have a 2012 Jayco Eagle Light 298RLDS. Overall, very pleased with this trailer. Trailer is on a seasonal site, 150 miles away from the nearest Jayco dealer. I used the furnace in the spring and it fired up as needed. Went to use the furnace a couple weeks ago and it wouldn't light. Blower starts up and there are a few clicks. Can smell propane coming from unit when I'm outside. Fan shuts off after a bit. Was at the trailer this past weekend and tried the furnace again....it started up and produced heat. The next day no luck....furnace wouldn't fire up. Of course my dealer will cover the warranty charges if I have a technician come out from a different RV dealer....who is about 60 miles away. Travel fees won't be covered. Any suggestions as to what I might try?

Propane full? Stove lights? Might need to purge the lines a little
