Two years ago we started on a trip to Missouri, and the first day out we smelled ammonia in the Dometic fridge. We made the rest of the trip with coolers and ice, and when we returned home I started looking for a replacement. I had formerly worked for Dometic in their Service Dept. so I knew a lot about absorption units, and I decided to get away from these. We have a 2000 watt inverter and a 255 amp/hour house battery, and we rerely dry camp, so I knew we had the means to run a house type refrigerator.
I ended up getting the Frigidaire model FRT045GB, a 6 cu. ft model, which fit nicely into the same cabinet. I paid about 1/2 of what it would cost to repair the cooling unit, and about 1/4 what a new fridge would cost. We are very happy with it, and it works very well - cools MUCH faster than the absorption types. I have closed off the roof and side vents as the unit is ventilated to the inside of the coach. I replaced the side vent with a baggage door to give us some storage behind the reefer. I have posted pictures of my installation at: http://www.gmcmhphotos.com/photos/showgallery.php?cat=5264
Our inverter has a modified square wave output, and the fridge draws almost twice the normal amps when running off the inverter, but it seems to work just fine. I would suggest that you consider the true sine wave inverters if you plan to go this route.
