I do not know about the 25J but I removed the couch (actually is was more like a sectional) in my 35G and replaced it with recliners. So much better in my opinion!
Ditto. I don't know about the 25J either, but I replaced the sofa/sleeper in mine with recliners and it was a great move for me. In 15 years of ownership we only used the sleeper one time. It was horrible and both the sleeper and couch were very uncomfortable.
