Here are a few pictures of the sofa I built for our 32MK. Had to build it in 3 pieces to fit behind the facia of both slideouts. I also had to relocate the heater vent. I'm still not sure what I will do to modify or replace the side valances on the back window.
This shows the storage below the seat cushion which is 34.5 x 29.5 x 15 inches and the storage behind the back cushion which is 6 inches deep at the bottom and 4 inches deep at the top.
Clearance to the carpet of the entertainment slideout is less than 1/4 inch.
Each side table has two lids that are hinged and removable as the next two pics show.
This sofa is 6ft long so I can lay down while watching TV. The factory sofa has been removed and the recliners now face directly at the TV which is so much better. And now the recliners do not have to be repositioned to close the slideouts, the only thing that has to move are the ottomans.
