My apologies in advance if this topic has already been discussed to death My wife and I have been live-aboard cruisers on our 37' sailboat for the last 8 years. We bought a Toyota motorhome last summer and are doing a few things to make our lives "aboard" easier. We have really liked our 12vdc refrigeration on the boat for many reasons. We're beginning to look at changing from our old and tired propane / AC refrigeration to a 12vdc system. We'd be interested to hear of any real-world experience any of you might have regarding using 12vdc refrigeration in a Toyota RV. We already have 2 120w solar panels, a Frigiboat compressor (we'd need to add the fan cooling add-on to the compressor), and a pretty good sized evaporator. Here are a few of the many thoughts we've been tossing around: - The boat has a house bank of 6 Trojan T-105 golf cart batteries for a total of 675w of 12vdc power. I won't even consider using this much storage on the RV due to the weight, so I'll need to come up with a reasonable compromise. - Our most desirable camp sites tend to be in the shade. - On the boat, we'd often sail for days on a passage and the panels and wind generator would keep the batteries charged (unless we had to run the water maker and the sun wasn't out). This included the additional loads for navigation equipment, radios, and nighttime running lights. - Our fridge on the boat ran at about a 1/3 duty cycle, drawing about 40 amp hours per day. However, we should be able to build a better insulated efficient top opening fridge than the one on the boat. It will fit in the same or less space than the current 120vac / propane fridge. - We'll be running the engine in the RV more often than we did on the boat, so the alternator will take care of some or most of the charging load except when we stay in one place for a while. ... and so on.

Greetings, I was just offered an opportunity to purchase a Dometic RM 760 three-way two-door fridge / freezer used for $100. Assuming it works, is this a good deal? The owner is willing to guarantee it to cool properly on 120v AC, 12 VDC, and propane. Is anyone familiar with this model? Any thoughts on how efficient these things are? Thanks.
