One other discovery was made on that trip.  The refrigerator quit the night before we got to Oshkosh. We got a service man out and he had it going in just a few minutes.  He showed me a reset procedure.
I think it is blowing out on the road, trying to relight, blowing out again causing it to lock out.
 
When we got home, I decided to check the procedure on the original board we had replaced a couple years ago when it quit on the road.  Sure enough, it fired right up.
Now I have the original board, a spare Dinosaur board and a 2 way board (that was installed in an emergency a couple years ago).
I think I have spares covered.
