We have had our 3260 for one complete season. We are not fulltimers. The middle island thing, makes it so you cant access anything without the slides extended. One switch for the bedroom slide(electric), and another one for the other two hydraulic main slides. The only thing I have noticed is the tanks on this rig drain so slow, compared to our elkridge we had before this. We also removed the bedroom, and bathroom doors, we found them to be in the way. By removing the doors, the hallway is much easier to navigate.
We also went to furniture row, and replaced the couch, and recliners with better more comfortable furniture.
The only odd thing, is when the bedroom lights are turned on, our TV reception dies. There is a thread on here, concerning this issue. Seems like its a 3260 only issue? Also we didnt realize this, but because the super slide is so tall there isnt any room left for a ceiling fan...so for sure get a super fan on your options list for the living area. Anyway we really enjoy the roominess. Man this coach is big inside.
