We have a 2019 3120 that uses about 55amps, drawing from the OEM 110v inverter. When boondocking, we run on propane overnight and usually between 10-11am, our 1500 watts of solar is producing enough amps to replace what we are using, plus some to recharge from overnight usage. During the winter, we use about 90Ah per day and during summer its more like 60-70ah per 24 hour period. Once the late afternoon comes around, maybe 4-5pm, we switch back to LP gas. A 9kg bottle which is the standard in our Country (NZ) we can extend our LP usage from one bottle every four days to one bottle every 5 to five and a half days. I've read about the 12v compressor fridge conversions, and am very tempted to buy one, but while this one is working well, LP gas is a convenient alternative in the mean time.
