Greetings Dean!
I am sorry that you have had bad experiences with the 12-volt side of RV
refrigerators. I am on my second, and wouldn't voluntarily have any other
type. Each of mine has been a 3-Way (1980 Dometic 3-Way and 2001 Dometic
3-Way), but I wouldn't hesitate to consider a strictly 12-volt if the size
were correct. My current Dometic 3-Way was installed nearly three years ago
in my Overlander as part of its restoration, and it has only been operated
on LP for at most three hours (shake-down to be sure that it worked on LP)
the balance of the time has been on 12-volt or 110 AC. I always tow with
the refrigerator on 12-volt mode and have always had perfectly cooled
conditions in both the refrigerator and freezer - - even after twelve hours
of travel with 98 degree heet and 99% humidity. The only shortcoming that I
have experienced is that it can take up to 36-hours or a bit more for an
initial cool of the refrigerator if done on 12-volt.
