We too have the Sport model and the 6" width hasn't been "noticeable" to us. There's just the two of us so we only need one sleeping area and we opted for the slide out "living area" without the dinette booth. The only times I've noticed the lack of those six inches is when I'm backing into a tight spot or storing it in my garage.....The standard model would not have fit, and that would have been a big problem.....

BTW, the factory width dimensions seem (at best) to approximate the width of the "box" but do not take into account the additional 4-6" that are gained by external fixtures and the awning......
