Any Bumper Pulls with Rear Living and Bunkhouse?

If you are open to a bumper pull toy hauler with a separate rear garage that could be your bunk room, check out the Keystone Carbon 33. Plus you can get a rear patio kit.

They have heavy tongues and I'm not sure the specs of your 2500, but it should be within your ratings if you have one of the newer 2500s with the 1800 lb receiver.
