I would check out the Passport 2920bh
That is the camper we bought this year so all the kids could have their own bed. It is 29ft box and 31 over all. It pulls like a dream also.
Its under 5400lb dry too
During my search I narrowed it down to the shadow cruiser and the passport and the passport won for 2 reasons
- the frame was much more stout then the cruiser
- the beds were 32 inches for all 4
One caveat is that the mattresses are horrible on the bunks in both trailers so I am going to buy foam and put it under the mattresses.
If the bed size and frame don't matter the shadow cruiser was nice and it was only 28ft box and 30 overall
