Wow, lots of great advice and opinions. I did find out that Tiffin (and others?) used to add extra batteries with the residential fridge, but in the past few years they (and pretty much all manufacturers) just put in 2@12V. Same thing you can expect in a $15k travel trailer, so much for "high end".
Rather than quantity of batteries, they may have increased the battery size. I know some of the 5ers that started offering a residential fridge went from the initial 3 24 series 12-volt batteries to 2 31 series 12-volt batteries.
