We've really enjoyed our 15BH. It's tiny, and we haven't minded. Local weekends and short trips are fine. It was a little cramped for our 42 day trip this past summer, but not miserable.
That said, we are ready to move up a bit in size. We really like the 22RB models with U dinette slide-out.
I feel like the bunks have more cons than pros. First, the kids are growing like weeds and already touch the walls head to toe (they're only 10). Second, the bunks are wasted space when not sleeping, and in a smallish trailer, that's a large portion of real estate. Lastly, as the kids get older, they like sleeping on the couch and floor, even when home.
So here's the question: What do you think about a family of 4 buying a trailer with no beds for kids? I'm thinking that with a slide out dinette, there is enough floor space for kids in sleeping bags. If the weather is ideal, they might even be in a tent. We could always fall back on converting the dinette if they had to have it.
Why? because the floor-plans have such better living space without bunks, and I can see that we're 7-8 years from not having the kids all the time.
Anyone out there putting the kids on the floor? How's it working for you?
