I just traded in a few weeks ago, our 2012 Georgetown 351DS with bunks that was an awesome unit, and served us great for 9 years. Now own a smaller Newmar (see signature), as kids no longer camp with us, and could no longer fit in the bunks, anyway.
I would agree with the previous comments about avoiding units like the ACE that have questionable build quality. One thing I learned over the years with the Georgetown is that you really, really do get what you pay for when it comes to RVs. There's a lot of units out there that ain't built too well. If you can afford a unit like a Tiffin or Winnie (or even Newmar) that is known for better quality, you really should go that route.
And, yes, there are LOTs of Class A options out there with bunkhouse floorplans. Especially ones built in last 10 or 12 years.
