We were back and forth between the 23B and the 23F. We have 2 kids and decided that the 3 queen beds were the best option, so we don't have to break down and rebuild the dinette every night (which is not a big deal, but it's nice).
Also did not like the fact we would have to climb over the dinette every time we got in and out of bed in the 23B.
Definitely made the right choice, we love the trailer, it's huge inside, and the deeper slide on the 23F seems to make it feel a lot bigger than the 23B, even though it's not.
The salesman told us that the 23B was the all time best selling hybrid floorplan ever. This poll seems to back that up...
