Here's a link to the 2005 Itasca line brochure showing our Class C. Take a look at the floorplan (Page 5), the specifications/features (Pages 7-12), and the photos (to see the crowned - not flat - one piece fiberglass roof with rolled edges all the way along each side) of our 24V model that Winnebago no longer offers. They offered the 24V floorplan up until recently, but at a lower construction and fitment level than they did back then. About the last year they offered the 24V quality level of what we have was in their 2006 "Outlook" line. After that, I don't feel that their 24V floorplans were as well outfitted and constructed. Ours is on the optional E450 chassis and is a non-slide - the two things we wanted for offroad use when rockhounding in remote places:
