I've got a Resi fridge in my TT, and I'm very happy with it. We are normally in a campground with power so batteries are not really a concern. I have 2 golf cart batteries, and they run the fridge fine, while driving the truck keeps them charged, and the batteries last overnight easily.
We keep the camper at a storage lot, and when I get to the lot I flip on the batteries, and the inverter, and by the time I get hooked up and drive the 5 miles to the house the fridge is already getting cold. No need to go by the storage place ahead of time like with the propane fridges.
Also you can camp in 100 degree weather, and still have ice cream with no worries.
