Looks like the Whitehawk 28DSBH and the Jayflight 28BHBE have the same floorplan, the Jflight being heavier. The Jayflight 28 BHS is a bit shorter and lighter then the Whitehawk. I can only add that our 28BHS is over 3 years old now and has been a solid unit with a large L shaped kitchen. The slide is shallow, but everything is accessible with it retracted, even if the couch is folded to a bed.
