Thinking about a Cougar 29RBK, why the East vs West?

[aclay]

I'm new to these forums. We currently own a Jayco 26BH and really like it, but want something bigger. We like the layout of the new 29RBK (bunkhouse with outside kitchen). It seems this is new for the west coast (we live in WA state).

I like the look of the Xlite version, but they don't offer those out here. Anyone know why there is a different version for East vs West?

I'm looking forward to learning more about Keystone products, any advice would be appreciated.
