yep, we have a '07 Rockwood Roo that has the '06 interior decor and fabrics.
as was said, it's pretty common. that's why you should make sure of the manufacturing date. if next year's model is getting some upgrades, some of the first ones may have been built with the previous year's features.
congrats on your new to you hybrid!
be sure to post on the Expandable section here at FRF. we hybrid owners can help you with the unique features that a hybrid offers.
