In the process...
I too am now replacing the couch. Putting in 2 recliners. Plan is to build a very small side table with the vents installed there. As part of this project I removed the shelf that was behind the couch and replaced it with a chair rail to give better depth to the platform and hence less furniture sticking out into the aisle. I will also be moving the seat belts. We are now parked for the winter, so lots of time to do it right. BTW, found Ashley Composer power recliner that fits through the door! Cheapest overall price was at Goedeker's.
