am using my first residential fridge now and really like it...
I run 2 group 31 batteries with a 1000 watt pure sine wave inverter..
I have had zero issues , I do keep it in my driveway for storage , so pre cooling is not an issue.
We usually run 8 hrs. a day on the road , but depending on time and vacations, run harder to get home.. We left Sarasota Florida this summer and drove straight up to Doswell VA.. (about 15 hrs/900 mile run) Once there , the bats were at 100% from the truck.
We already decided that the pros FAR OUTWEIGH the cons , and will get another one when the time comes..
