It went down to 48% and I had it filled back up. Anyway, for the present time everything is running fine. We will see what happens tonight.

I have the 2015 version of your rig. Had a similar problem. Would work fine above freezing but shut down or almost down when below freezing. Got an injection of Methanol from my propane supplier and no more problem. Since you are now working at 12 degrees may not be the same problem, but I would still get the methanol. It won't hurt and might help now or in the future. Not all propane dealers do the methanol. My dealer did it for free but $20 seems to be about normal.
