3120rl

What are the differences between a 3120 rl and a 3121 rl?

I believe the last digit “0” means it has a RV gas/electric fridge.
The “1” means it has a residential fridge.
My rig (3921 FB) has a Samsung RF18 residential fridge.
No idea if this numbering is still used on newer year models.

At one time the only difference was the 3121 included a residential reefer.

On new units they have the same designator now. No model.differences between residential and RV (now 12V) refrigerators. Now one has to look at the build sheet to know for sure. I'm of the understanding that std fridge is residential and 12V is optional.
