K-Z Durango 2500 line does have a few models with such a closet, it is also the optional W/D location. I would like to see one in person, but they seem to be pretty rare. I'm not aware of any other brands with full depth entry closet, it is even hard to find units with any kind of substantial closet near the entry door. Hopefully someone else has other inputs.
