I have found that the newer fridges with the circuit board and electronic ignition don't blow out anything like the old ones where you have to ignite them with a push button. The Dometic in my 2009 Apache has never went out on the road that you would notice anyway up to 70 MPH. The downside in the fridge draws a small amount of power all the time to keep the board alive
The old one I had before needed constant monitoring and relighting all the time.
I have 8 Ga charge wire and a 50 watt solar panel I set out and have boondocked for days with no problem.
