Just purchased a 2019 Montana High Country and one of the selling points was a residential Fridge. Not having that much knowledge about new upgrades over the 2007 Jayco Designer we were excited to see suck a large fridge/freezer. The old one we could switch to gas on fridge and not worry. Of course these have no gas option so I’m concerned about travelling and worry about the thing thawing our. When we head south for the winter from Ohio we usually stay overnight at a hotel the first night. No, without being plugged into anything how long will it maintain the cold and frozen stuff before running again. We have no generator. Thanks
Can't tell you without knowing how much battery capacity you have, or how much current your inverter/fridge combo draws.
But with a little pre-trip experimenting you can figure it out. Safest thing would be to turn off the fridge when you park for the night. Then don't open the fridge door until you are ready to power back up the next day. By safest, I mean the least chance of running your battery bank too low and causing shortened life span. Not as safe for the cold food, but most fridges are insulated well enough to handle 8 hours turned off without harming food.
