We totally flip flopped the inside of our 5'er. We removed the booth dinette from the slide and the rear crappy sofa sleeper. We bought a table and chairs from a local furniture store and put those in the rear so we now have a rear dinning. We then bought a nice recliner theater seating love seat. We put that where the booth dinette was. Depending on the views or whatever we will move the sofa to the rear and put the dinette in the slide. I like the versatility.
I had to patch up some holes and extend some trim in the slide area. Bought some wood at Home Depot and found some stain to match.
