I purchased this to replace the AC/DC/Propane refrigerator which was in the Minnie Winnie RV we are restoring. The old 3-way power refer no longer worked, and a new one like that is more than three times the cost of this one. This fridge fit right into the same cabinet the old one came out of. The height was perfect. It is just a little narrower, but actually has a bit more interior space because the depth is greater. To fasten it n place was easy. The back is on two rollers, and there is a convenient hole next to each. I bolted it down through the floor of the cabinet. The front has leveling feet which screw in and out. I took each out completely and then screwed it back in through a steel angle. The angles fit against the front of the cabinet below the opening and are screwed in place. To keep it from rocking I put a piece of foam about 6" square on each side near the top. It is solid and still has good circulation. I used some trim to cover the gaps on the sides.The refrigerator works perfectly, and once we adjusted it the fridge part is in the high 30s while the freezer hovers near zero. A compressor fridge like this just cools better than a propane model. We boondock quite a bit, so we need to be able to run this when camping far from shore power. I'm an electronics guy, so I did some testing. This draws 70 watts when running, but it doesn't run all the time. At 80 degrees ambient temperature it runs a bit less than half of the time, so it draws only an average of 30 watts or so. Now, 36 watts is 3 amps at 12 volts. Three amps times 24 hours is 72 amp hours, and I am using a really good AGM deep cycle battery with 85 amp hours.However, I also have 200 watts of solar panels on the roof of the RV. To keep the math easy, figure they average 144 watts for 10 hours a day. 144 watts is 12 amps at 12 volts, times 10 hours, means I am getting 120 amp hours of solar charging, which is well over what the refrigerator is consuming, so, in practice, my battery stays full. If I get a few cloudy or rainy days, I just start the RV and let it idle for a little while. When the engine is running it charges the house battery at about 50 amps. Even on a cloudy day I still get quite a bit from my solar panels and it isn't cloudy all that much here in the southwest where we live and camp. The power for the fridge comes from a 1000 watt pure sine inverter.We did have to install some eye bolts so we can run a bungee cord across the doors when we are driving. So, now we have a great fridge, no need for a generator, and I can enjoy an ice cream bar when camping in the middle of nowhere. BTW, this arrived early in perfect condition, and the delivery guy even helped my unpack it and put it into the RV.
