I’m thinking of converting to a 12v as well. Is there any advantage to getting a model that can also be powered by 110v? When hooked to shore power I believe my IOTA converter would still supply power, either 12v directly to the fridge or by trickle charging the battery that then feeds the fridge. My longest trips are usually 2 weeks and I only occasionally use shore power at a campground and for charging before before we leave. The 110 models are a few hundred dollars extra and I don’t know if there is any advantage to them in my situation. I have 100w of solar and don’t stay put for long so I’d be getting trickle charge when driving.
