Hey there,
We bought that model brand new in '08.
Very functional for us as we have 3 boys, with the oldest being 6'4". That is where the 7 foot top bunks were awesome.
When I saw the rear king bed it was a no brainer for me too....I'm 6'2" and loved the length.
As for the trailer, it was very well built, and any issue we did have was handled by KZ with no problems.
Functionally, the only thing we found was a bit of a nuisance was that we didn't have a spot to get changed as our bed was at the rear and not a 'room'. Solved by waiting for the boys to clear out and use the bunk room as the designated change room.
U dinette was great, the two entrances turned out to be very handy.
At that price I think you will be very happy.
Mike
