This is a common upgrade.
Recpro, and other rv furniture makers/sellers offer a pretty good selection. Measure your space and take into account the distance a recliner must be away from the wall to recliner, they vary, so you know how far it may extend into your walkway. You'll want to preserve some space for a person to pass I assume.
Also, understand how it attaches to your floor space, if on a slideout or not. Some folks have just set them into place and claim it's just fine. I had mine installed by my dealer and attached to slide-out flooring so I can use the seat belts. BTW, because some recliner seating surfaces are taller than stock sofas you may need seat belt extenders - I did my old sofa was very low.
