In 2003-2006/7 the Minnie Winnie & its twin the Itasca Sundancer were the top of the Winnebago Class C Motor Homes. If you find a good condition Sundancer you will enjoy it.
Some info on Winnebago 2000 - 2010 Class C Motor Homes On Ford and Chevy Chassis. In regards to Winnebago and its twin Itasca you can go to www.winnebagoind.com click on Resources and then Manuals and Diagram and download a Pdf brochure and spec sheets for the models and year you are checking out and see what is standard and what options are available.
A little background on the models: W stands for Winnebago and I stands for Itasca. Both have class C model numbers 200, 300 and 400. 400 was used with the top of the line class C the W Minnie Winnie and I Sundancer. The Minnie Winnie’s last year was 2006 and the Sundancers last year was 2007. These 400 models were the top of line in Class C’s, For example a Minnie Winnie 30V full model number is WF430V and the I Sundancer 30V is IF430V.
The next level down is the W Minnie and the I Spirit. These are model 300. W Minnie is not a Winnie Minnie, but some people call their Minnie a Minnie Winnie. The Minnie label changed to Outlook in 2006 and offered many of the features and options of the Minnie Winnie/Sundancer, W Outlook and I Spirit were offered through 2010. As an example the Minnie/Outlook 29B full model # is WF329B and the I Spirit 29B is IF329B.
The next level down. In 2007 W & I brought out the new entry level Class C the W Access and I Impluse both model 200’s. For example the Access 31C is WF231C, and Impluse 31C is IF231C.
Winnebago Chalet brand is built for the rental companies, not sure if they follow the same 200, 300, 400 numbering system. They are about the same as their other Class C’s except more basic and no carpet.
2011 Info the Outlook and Spirit are gone, replaced by W Access Premier, I Impluse Silver.
I hope this helps and does not confuse you. Good luck RV hunting. My only other comment is
don’t count on a RV salesperson to know anything about the RV’s they sell. All they know is that they have the perfect RV for you on the lot and you can own it today. Do your research prior to shopping.
Good Luck
