We mainly boondock. My current trailer we are selling has the typical 2 way fridge, so we run the propane for that. I added a 100 watt solar panel and 2 T-105 batteries and never have any issue with electrical needs. But the more and more I dig into the 12volt fridges, they are primarily for shore power it seems. I talked to the salesman again who stated there is a solar panel on top, the charge controller was supposed to be in the storage bay, which I don't recall seeing while I was looking at the unit. I asked them to send me a pic of that and they were also looking if they have a 2 way fridge option. This at the time of typing was 3 hours ago, not thinking there is a charge controller. But then they were also stating this fridge can run for 3 days on these batteries before batteries need charged. After doing more and more research I am just not buying that pitch. Everything I see shows it will drain these batteries in 6-12hours, and this unit has a smaller outside fridge. It would need a lot of solar and a big battery bank to maintain this. I am passing on the unit.
