I took mine out, put a regular fridge in its place. I don’t like the propane on if I’m sleeping in it. I use electric heat also.
That requires 120v, not available on most of our camping trips. Also, regular fridges can't take the shaking that a real RV fridge takes. Those are made for washboard roads. That's part of what makes them so expensive.
In trying to fashion shields for the refrigerator flame you may actually be causing a vacuum in the compartment which is sucking the flame out. If the access door is original, it should stay lit while going down the road. I have two travel trailers, oldest is a 2000 model and they both work fine.
The fridge isn't original and possibly it doesn't fit like the original did. It blows out with no shields and I've tried any number of tricks to shield it without success. One thing I haven't tried is blocking the outside door completely. It's open underneath into a large space and has a vent fan above it so it will still get plenty of air.
