Our 1990 H33 came with a Norcold, which was the bane of my existence. I hated the thing, and it drew an incredible amount of power. I told the other half, "We are ripping this out!" We ended up putting our Engel from our other boat in the quarter berth (this thing is amazing- it is about 10 years old- our complaints are, "Oh crap, I turned it down too low and everything has formed ice!") We have 2 old 20W solar panels (we have not upgraded with our new ones yet, as we need a new arch to do so), which outpower the Engel when we are not at the liberty of shore power. Seriously, if the Engel goes to hades, I would buy another one in a heartbeat. As for the old "refrigerator storage area"- it makes good storage for extra provisions/drinking water.
