I also have a 3 way in my Bobcat. While on 12v down the highway I notice a battery drain also.oldebondo said:I have a brand new 2016 Hawk with a 3-way (standard equipment) fridge. The truck is a 2016 F-150. Here is my disappointing experience: If I switch to 12V while going down the road, the on-board (single) camper battery will discharge roughly 50% per day of travel. When I switch to propane that night after travel and then switch back to 12V for a second day of travel (i.e. two days of no shore power), the on-board battery will totally deplete to zero. Yes, I can hear the relay clicking ON when the truck is started and I can see charging voltage applied to the on-board camper battery. Yes, I always start the trip by running the fridge on 110V shore power the night before to cool the fridge down. The FWC dealer is suggesting that the fridge consumes more power than the output of the truck charging circuit. If this is true, what good is it to have a 12V option on the fridge? I think there is more going on than I understand.
My workaround is to use propane while going down the highway which seems to work well.
Has anyone had a similar experience with their 3-way?
I have been just using to propane all the time and that works better.
The "pilot" light size flame to run the fridge uses very little propane.
On our Alaskan trip I got at least 21 days from the propane before it needed to be refilled. That's fridge (24/7),stove ,and heater when needed. I have stopped using the 12v it's a waste of time.
But I also have a Truckfridge.compressor cooler and it will run @35* for almost 5 days without and charge going to the 100a battery.
On the long 5 night ferry trip the cooler with the voltage cut off set to the high setting ran for a few hours short of the full 5 day
trip.
