Everything including the kitchen sink!
We have added both a Nova Kool R3800 12 VDC refrigerator and a galley sink! We are almost complete with the inside work for Phase 1 of our Tripper DIY RV!
Our refrigerator is a Nova Kool R3800, 12 VDC ONLY! Run’s off the house battery, and uses the efficient Danfoss compressor. According to our battery monitor it uses ~35 watts when cooling.
