In case anyone subscribed to this & is wondering what happened, I thought I would provide an update.
We ended up purchasing an Outdoors RV 26F. It has a double bed in the rear with a single bunk over it. This winter, I'm going to convert the single bunk to a double - matching the one beneath it. Then, the kids can double up in the double bunks!
We're really happy with it so far. It seems like a VERY durable unit and roomy enough for our family. We've been adding/modifying since it was delivered a few weeks back! It has only been out for 2 nights so far. We boondocked & everyone had a GREAT time.
