I've never seen the this floor plan in a Chinook but it's a shame they got away from it in the newer ones. The kids bed above the cab is a stretch for a bed but offers tons of storage that Chinooks don't have. Also, the lower cabinets/countertops and U-dinette are far more user friendly than the newer 2 floor plans and you can actually walk through with the bed made.
Neat rig, thanks for sharing.
