Just for fun I looked through the pages of Diesel Motorhomes <$100K on PPL motorhome's website. I did not see any with bunks. Several had the back bed (Queen or King), 2 sofa sleepers, and a booth dinette.
I think you're going to have a hard time finding something in that range with bunks, but some searching might find you a unit with a floorplan where you could have some feature removed and bunks installed. Would just take a lot of looking at dealer websites and some time.
For more fun, I found this model...new and way above $100K...that basically fit what you said you're looking for in length, DP, bunks, etc. So what you are looking for does exist.

Looking and searching is kinda fun anyway. Good luck!
