I had the same problem, but occasional.
I have two tanks of propane on my Trillium
and when I moved on the road, everything was o.k. or the pilot went out. I deducted that when the tank of propane which I used was a little bit low, the pilot went out by moving me and when, before moving me I transferred on the full tank, the fridge worked normally.
Possibly my regulator to be replaced for the next season...
