household fridge

I'm cuurently building a class 'b" rv from a high top ford. Is there a downside to using a small (dormsize) fridge? I'll be using a 400AH battery bank, with wind and solar plus shore power when available. Is there a reason few people use household fridges? Thanks, Kurt

  • This is something I have done. There is a problem that can be covered and that is that dorm reefers use the sides as condensers (where the heat goes out). Sot they must have air space on the sides to cool effectively.

    And yes, there power consumption can be high, but the government mandated energy labels can help you a lot there. Don't blow by and not look at them. If it isn't at least Energy - Star, you don't want to try to run it on batteries and solar.

  • Does the dorm size fridge have a proper freezer? And, is having one important to you?
  • A household fridge will also exhaust heat to the outside just the same as a RV fridge if there's a vent. Even if that was an actual issue, it would be an extremely minor one since you don't have a burner on a HH fridge like you do with the RV fridge.
  • It will only run on 120v AC(I need my batteries to last as long as possible), it removes heat from inside of fridge and puts it to inside of rv. RV fridges put the heat to the outdoors, and you will have to put a latch on the door to keep it closed in transit
  • I run a 120V 1.7 cu. ft. dorm fridge with solar, an inverter, and 310 AH capacity. It draws 80W, about the same as a newer, medium sized unit. If I ever get into the chips again, I'll probably replace it with a 12V fridge. The good 12V fridges use even less power.
  • The dorm size fridge would also be considered a household fridge. It runs on electric and not propane so no fire danger and much better performance. You should have no issues with a small fridge.
