Really liked the front living room floor plans when they first came out...
After careful consideration, ended up not picking one because of the lower ceiling height in the living area. Even on a "tall" 5er, it felt claustrophobic.
Regarding the living room seating position (regardless of front or rear floor plan), we really like the RV on the front or rear wall - as pictured in this thread. Some indicate that that TV viewing position is 90 degrees... While it is, I do not find this to be a problem, when I crash on the couch (or in my chair) i CRASH on the couch and many times, lay down.. LOL...
One nice thing about that arrangement is the opposing seating config - especially with the opposing slides. Gives a very large space when people site face to face and they're across the room.
