We just bought a L440 as well and we're looking at doing some modifications, too.
I was thinking about removing the bench seat in the salon
and replacing it with nice square solid stools that have storage
space inside. There are few hand-rails while underway, but for living aboard
I think we'll want the space.
What do you think?
Also, I was thinking about the couch, too. Even if there were a way to create more storage
space underneath it may be worth keeping it.
I think the nav station on the L440 is actually pretty decent. It's facing forward and rather large.
