One of the guys at "appy time" mentioned that I should probably mention the power savings as well by going to a residential. A residential fridge uses about one fifth of the power of an RV absorption fridge. SO extrapolating at 11 cents per Kilowatt hour (British Columbia Rates) it would save you about 150 bucks a year in power. Depending where you are that may be higher or lower.
Please feel free to pick my numbers apart as I kinda suck at this. Our fridge is rated at 366 KWH per year so roughly 1 KWH per day or 11 cents per day. If an absorption fridge uses five times the power then lets say 55 cents per day or 44 cents per day more. So roughly 13 bucks per month or 155 bucks per year. That offsets some of the costs of the change over. Of course we are full timers so if you are not these numbers won't apply.
Honestly for me the savings wouldn't sway me either way. For us it is all about having double the space in a unit that just works better with pretty much zero maintenance year after year. Our Norcold was a money pit and a maintenance nightmare.
Again, no idea how accurate the numbers are although I wouldn't think they are too far off from measurements I have taken on residentials and absorptions. The "appy group" just thought it would be worth mentioning. :)
