I have a bunk house that is 32' long. Older, but lots of models with a similar design. I would definitely look at a bunk house or toy hauler as your kids will not get smaller, only bigger. Lately I really like the mid bunk, which might work great with a crib, but I think they are longer than what you are looking for, as are many toy haulers with a separate garage. All I can say, as is the kids get older, they need their separate space. So, unless you plan to upgrade again in a couple years, get what you need now.
