Good luck with your fridge,
My 1997 Xplorer 230XL has a Dometic RM2310 fridge which draws no 12v power when on propane making it perfect for boondocking which is most of what I do.  When I had a rust breakage problem with the flue and piezo lighter lining up, I checked into a new replacement, but with their electronic controls running on propane would draw 1.5 - 2.5 amps, way too much for my boondocking. 
I took it to an RV repair shop & they refused to touch it.  I was able to fix it myself and I am back in business.  I wish Dometic still made a model without all the electronic stuff just for boondocking.  I hope I can keep it going.
