Yeah, most of the RV makers are pretty casual about the model names. They come and go and get re-assigned to different models and even combined with other names just to keep everybody confused.
I have a Class A Coachmen "Santara" from the mid-90's, yet at the same time Coachmen also made a "Santara" model on the Class C. Totally different motorhome, yet the same name.
Also back in the late 90's, Fleetwood combined the upper-line "Southwind" name with the bottom-level "Storm" to create a new model, the "Southwind Storm".
I don't know what that was all about but they sold a bunch of them.
