Residential 10.6 cu ft frig

I've been looking for the same size (24" wx26" d) to replace my Dometic 2852. It's in a slide and the coach has dark sides. When the temp gets above 80 it can't stay cool. It's been replaced once three rear venting fans installed and three interior fans being used. I even purchased a unit for our bsmt storage to keep all the beverages so the interior of Dometic would have lots of free air flow. All to no avail. I've found two models of a 10 cu.ft. Frigidaire that has the width and depth dimensions that work. FFTR1022QB and FFET1022QB (energy efficient). Whirlpool and Frigidaire have 10.7 cu. ft. units 24" wide but 28.75" deep. Magic Chef has a 9.9 unit that is very economical that others have used but the owners manual states that it should not be used in recreational vehicles nor powered by an inverter. The 5 year compressor warranty would be useless. Hope this helps
