Is a toyhauler right for us?

The wife and I are currently looking at going a different route for our camping excursions. Currently we have a 33ft. Open Range 5ver with bunks in the back. We absolutely love the trailer, it's got 1.5 baths and great for the kids...until they got too big. The bunks in the back are perfect for kids up to the age of 10 but now the top bunk is pretty cramped for our youngest, enter discussion of the toyhauler. I've looked at plenty of trailers and almost all of those with bunks are suited for smaller kids and not teenagers. I love the toyhauler concept of two large beds in the back along with the deck concept out the back. We do have a fourwheeler and I suppose we would throw it in at times, but most of our camping is at the lake with our boat, so we really don't need the toyhauler for toys but for room and again, I love the deck concept.

My first question is do those that have THs, do you like the back space for kids or is it too "garage like"?

Second question, I do like the Keystone Fuzions with the slide out bedrooms, is this a quality trailer? Any known issues with Keystone?

I'm limiting my search to tandem axle trailers as I don't want the triple axle. Please give me any thoughts to consider, experience, etc.

thanks,
