OK, my 2 cents worth (I have a 2013 34 RLSA):
If you swap the couch with the recliners, the slides will not come in. Sure, you can do it and leave it that way while you are parked, but everytime you hitch up to hit the road, you will have to move the couch back into position opposite the TV. Oh and someone pointed this out but you do have to swivel the recliners and push them back firmly against the back wall to be sure the slide clears. Personally, while I would love to be able to swap positions of the couch and recliners, all that furniture moving every time I hit the road would be too much. So I live with the couch/recliner positions. And DW and I have come to love it.
We actually liked the couch/recliner positions before we got the unit. Our reasoning was: DW watches TV while lying on the couch and I from the recliner farthest from the TV. With the couch opposite the TV, she can switch from her head at one end of the couch to her head at the other and still see the TV. But after using the unit, she found she prefers the recliner over the couch for watching TV. (Not sure why??) So we do a little strategic rearranging and lining up of the recliners and everything works just fine. Happy with the floorplan as is!
