Is there enough usage history for 12v refrigerators to say one is better than the rest? I'm looking to replace my Dometic 2652 6 cu. ft. with Dometics "direct replacement" Dometic 8CU FT 12V DC COMP REFER DMC4081. We don't boondocks and run 2 12v deep cycle batteries so I don't believe the 12v will pose a problem. Anyone have any recommendations on the best 12v refrigerator to buy?
