IMO...there are lemons lurking in every product line...Just when I think I may want a new camper...you see on the forum someone is having an issue with it...sometimes I think, you might be better off buying a slightly used one, if you can feel comfortable with the seller...
My first was a Grey Wolf, by forest river. It was a chance for us to "tip or toe" into camping. It was great! We sold that one after 3 years and bought a 2009 Laredo, by Keystone...Love it! It has great upgrades from our first camper. The seller was very honest about the condition and we have loved it!
Now, as to your OP on floor plans...a friend of mine had a 5ver BH...both sides of the BH slide out and it formed a fantastic "room" for the kids. I don't know if that is an option for TT, but it would be one I would sure like to find!
Back to your question...ID your price range, look at floor plans and options and pick the one you like and enjoy!!
