2012 Greyhawk 31FK.
We bought a Klaussner Fireside reclining loveseat. Looking at the Klaussner website it appears the Fireside line may be discontinued. The do have other models that have about the same dimensions. Many of the styles have photos. I believe the rought opening for the J-sofa is about 62 - 64 inches. Our recliner is 60" wide and, looking at the invoice, 38" high and deep. It does cover some of the window, but we feel the comfort will be well worth it.
The Fireside reclining mechanism is a cable with "ripcord" handle next to the seat. There is enough room on the sides that the flip handle variety will probably work. The Lazy-Boy style handle might be tight.
I used a piece of OSB subflooring to make a deck for the loveseat since the pedestal in the MH is too short. After removing the J-sofa I put retainer nuts on the bolts so they wouldn't drop our while working and eliminated the risk of jamming the slide. I drilled holes to match the J-sofa nuts and used fender washers to spread the load. Before mounting the OSB I aligned the frame members of the recliner so it was straight and marked on the OSB. Then I drilled for u-bolts that come up from the bottom of the OSB, bolted the OSB in place and the aligned the recliner tracks between the u-bolt ends. I used plates that came with the u-bolts and nuts with nylon locks to secure the recliner. The OSB is about 1 - 1-1/2" back from the front of the recliner so heels don't catch.
We are really looking forward to spring to start using the MH and new recliner. Our pug likes to get up early; the recliner will be much more comfortable as I catch a few more winks!
