SBx2, they are beautiful units. I have been in touch with Forest River over these issues.
1. They will put in a drop down dinette to replace the table and chairs
2. They are currently looking to increase the size of the front slide outs to fit both sleep sofa's. I spoke to a dealer they have a 2013 with 2 sofa's with air mattress but with the air leak issues I have had with my current unit I would never go back to that style.
So I'm keeping my fingers crossed that the larger slide outs will work with this unit. And if so I will be a owner of a 366FL shortly.
