I don't own either one, but I sure prefer the BL with the midships bath and a half dinette up front. The KL with its aft bath would be a PITA in the middle of the night near the other person's head.
Some used prices exceed new, so shop carefully. A quick perusal on RVTrader indicates a new one can be had for about $200K. When I was seriously shopping last year you could find a new MH as cheap as almost any two year old model. I bought new.
