The
2007 Adventurer Brochure lists
Window (Passenger) full-slider w/screen, dual-glazed/thermo-insulated as standard. So does the
2007 Suncruiser Brochure.
The
2007 Voyage Brochure lists
Windows dual-glazed/thermo-insulated as part of the optional Grand Package. The
2007 Sunrise Brochure doesn't actually list them in the optional Grand Package, but I suspect that just an inadvertent omission, since I would expect the Itasca model to match the Winnebago one.
I presume the 2008's would be similar, but I didn't check the brochures.
