production numbers or percentages for 320 and 400?

I do think of us as one very happy NuCamp T@B family, but we are composed of several sub-groups.  As I continue to work on modifications to various systems I realize that 400 owners have different stock and modification options than 320 owners -- For example, I didn't know until recently that some have larger stock AGM batteries.  Well, and more obviously, boondock owners have more storage bin options.  I am just curious -- does anyone know what NuCamp's model production numbers are?  Or at least what the percentage of T@B's in each group is?  Would be fun to know!
