Not sure about the 366, but the 356qbq is a nice trailer. Had mine 2 years and really enjoyed it. The space is nice, the 2 bathrooms are nice. Tows well. Both are big trailers .

After looking at both at the dealer, I wasn't very keen on not being able to access the front bedroom with out moving the slide out. The 356 seemed to have everything we needed.

That was one thing I looked at too. The ability to use the camper while the slides are in. The living area is small, but you can still make lunch, use the front bathroom or go in the back door for that bathroom, use the front bedroom also.
