It is the 3400 - which is the rear entertainment. We looked for months before we decided on this unit. I highly recommend Sanibel - in any of the 3 major floorplans, 3400 was our favorite. While it isn't perfect, on a scale of one to ten I believe we found an 8. That's pretty high up there. I recommend that when some one wants to buy a full timer, number one make sure it is full time warrantied - Sanibel is. Then list the needs, below it, the wants or extra's you desire. If you get 8 out of 10 you have a winner. The other option is have a unit custom built but then you are talking a significant cost increase. I believe that we have come pretty close to what we would have custom built in the Sanibel 3400.
