Remember that the buyers guide is sold advertizement for those who want to list their RV's in the guide. So if a manufacture does not list something, it is because they wanted to limit their expense to list it all.
Years ago, when I bought the guide, I was a little disappointed that my 30 foot Bounder was not listed. Then I found out that they work primarily on what the manufactures press release says, and base the artwork and floorplans on the manufactures advertizing department brochures. They did list about 3 lengths of each lineup, the Bounder, slightly more expensive Pace Arrow, and Southwind.
I always did enjoy looking over the brochures and buyers guide. It is fun to go window shopping too!
