I also own a Open Range bunkhouse and became interested with the idea of a toy hauler. I checked a few out at the Hershey RV show. In the end I still prefer the bunkhouse for kids. My bunkhouse is 39' so there is a bit more room vs. a 33' bunkhouse. My prior TT was a 32' bunkhouse and my kids did out grow the prior unit.
I consider Toy Haulers more flexible/versatile. The space can be adapted for lots of uses. However for kid space I prefer a larger bunkhouse.
While the bunkhouse is less flexible there is more dedicated space for living.
There are closets and cabinets for clothes and other storage. Beds are large enough for bigger kids/adults. The room does not need to be set up. The kids have there own dedicated space vs. a make shift space.
In the end I prefer the bunkhouse for kids simply because there is less work /set up to do. If you want/need the versatility the Toy Hauler has advantages.
I was intrigued by some of those advantages myself.
However if your usage is generally living space than I suggest sticking with a larger bunkhouse.
