LOL We went to RV shows. My dream RV is one where we can swap the queen for a king, but my wife doesn't want the size.
The big factors at the moment are:
Space for the kids (7 & 11 girls) where they have room to grow (we didn't think this through with the current 5th wheel bunkhouse - one bunk will be fine, the other, our 7yo will outgrow in a few years. The lower sleeping area is where our dogs usually travel and sleep.
Some degree of privacy for kids - for us certainly and for the kids definitely. Not a lot, but space where they can close the door and feel like they are somewhere more private than the family room.
We did like the layout and space in our older 29, but haven't found comparable models. When we needed (there were trips planned and we needed for the fair and shows) a trailer, the one we got seemed like the best of the options. Lots of models seem to give up bunk house space for outside kitchens and other things that are nice, but not as useful for us. The most recent find, the Jayco 29FBDS seems like a good compromise, but now... LOL
Perhaps I need to just let her learn to tow it and go from there.
