John (the OP),
You might also want to consider the 24V 2005 version of the Itasca we have on the optional E450 V10 chassis - it's been a great Class C for us since we bought it new. Note such things as tank sizes, interior wall construction, interior/exterior storage, and roof construction. The last year that Winnebago offered this same model with the same set of features was 2007. Don't look at this model earlier than 2005 or you'll not get Ford's great 5-speed (6 ratios internally) computer controlled transmission in it:
