I hit the wrong key on my first post! My 10 yr. old 12V freezer has finally died! Too many years (10 off and on) keeping the fish frozen in the Bahamas and the Virgins. I am looking for two things: What 12V, air cooled system is out there that seems to work well? How difficult is this going to be if I do it myself? A few comments, the freezer is top loading and is 2.9 CF, and I normally cruise the southeast and Bahamas.
