That model does not appear to have an awning that goes over the kitchen slide.
We are considering a Bullet 310BHS as our next trailer and does have an awning that goes over the slide. I have read that you DO want to protect the awning in cases where it goes over the slide.
For me, I think I can live with the slide taking a little bit of outside space in trade for the incredible amount of storage and counter space you gain with an island kitchen layout. Coming from a trailer with virtually none of those, that is what I'm most looking forward to.
