Good to about the anode rod, mine has one so I’m guessing it’s a suburban
Atwood water heaters ship without an anode rod because the tank itself is aluminum vs the porcelain lined steel tank used in Suburban water heaters that
require the use of an anode rod. That said, aftermarket anode rods to fit Atwood water heaters are sold even though they're not needed so if you bought your unit used there's nothing to say a previous owner couldn't have installed an anode rod in an Atwood water heater. If you bought the rig new then there's no reason an Atwood would have an anode rod so by definition if yours does have an anode rod then it will be a Suburban, most likely an SW12DE.
