Before we pulled the trigger on our 2017 28DSBH, we too were considering the 2704BH. On paper the lighter weight and arguably more durable roof appealed to us, and in online videos it showed nicely with the driftwood interior, etc. We also liked the taller slide out and the fact that it was carpetless. And the excellent R-values were also appealing. So we drove a couple of hours to see one.
In a word - flimsy. Pressed board abounded in the interior, the counters seemed to be made of an odd material, the walls are pinch rolled rather than vacuum laminated, fewer options are available, AND if equipped similarly the Open Range was more expensive. Yes, you're about 700lbs lighter, but you end up with a shorter awning, a plastic toilet, etc.
Lord knows the White Hawk is no Airstream, but compared to the Open Range we thought it was head and shoulders above it. Unless weight is seriously an issue, I'd recommend the White Hawk - more features, superior frame, more storage, better fit and finish, just a more solid rig all around. Oh, and less money too, at least in the head-to-head pricing we did.
I wanted to like the Open Range, but it just didn't feel like it would hold up over time. But everyone sees things differently, you might love it. Just make sure you stand in one of each before deciding. Good luck!
