Residential fridge and dry camping

Sounds like you already made your decision to go with the dual unit and that's fine they work ok. Personally I'll never go back to the RV refers. Had them in past campers and I had one in the present unit. I swapped it out for a residential unit and after using it for a few years now will never go back to the RV style. We dry camp, take trips on the road for a few days at a time, and have never had an issue. I actually think the RV unit drew down the batteries more. I have 4 batteries for the coach and a decent inverter, they all came with the coach so a swap didn't take more than pulling out the old and installing the residential unit and plugging it in. I've left it sit for 3 to 4 days with no hook-up and it barely phased the batts (I had moved it so friends could use our parking spot and forgot to plug it in). I'm done dealing with the dual RV units, I always had to plan and worry about the RV unit. The residential unit we start in April when I unwinterize it and don't shut it off until I close it up in Nov and never had any issues. Best mod I ever did. Residential all them way for us,but everyone has different opinions and circumstances.
