Removal of couch in toy hauler?

I am a newbie to RVing and beginning the search for a fifth wheel toy hauler to try full-timing. I don't have toys (I'm going to use the garage for business purposes) and I'm not a guy so I'm looking for a floor plan and decor that is a bit less of a "man cave" party place and more suited to everyday living. I've found a couple floor plans that are pretty close to what I would want and include a few important features (big kitchen, patio, w/d prep in the garage), but the giant couches are just too much. So... my question is, what is the feasibility of removing the giant couch and replacing it with something else (perhaps a small couch and dinette - space allowing)?

Also, if anybody has recommendations for TH's with floor plans that I should take a look at, feel free to lob them at me. Thanks!
