2019 Oliver Legacy II - with no inverter. I got the fridge going and am in hot temps (@90 degrees) and bright sunlight - and it is burning through the propane.The temp is set at 6 out of 9 with 9 the coldest - and is pretty filled up.
A couple of days running and one tank is down to 15%. The fridge is set to auto - and can be set to AC, DC or LP-gas. The manual says the DC setting works off the car battery and the car must be running - but I imagine and hope that it's drawing off the trailer battery. I can't tell if it's doing that, though, and if it is it doesn't seem to be helping much with the fridge (?).
The first person who bought the trailer put everything in it but the inverter - I don't know if that makes a difference.
Anyway, I don't know if blowing through this much propane is normal or not in these circumstances or if there's a way to stop the propane drain other than reducing the cold level of the fridge.
We just had the fridge in for maintenance, by the way, and it appears to be running perfectly.
