I looked at how I might add a recliner (we don't extend our L-shaped couch out with my DEQ and I move the recliner across the room to watch TV in a campground). On the road, we simply leave it on the slide and use the couch to watch TV with the slides in. What I decided is you could put a Euro-recliner (or some other recliner that didn't weigh too much in the corner of the couch while on the road.
In the end, I'll wait for a better floor plan, if a Cornerstone upgrade is in my future.
