You could take out the dinette and add a love seat. A few here have done that with good success. La-z-boy apparently is the brand since they come apart to go through the door.
I do like the looks of the Class A Toy Haulers, but they have relatively light cargo weights for the ones that I looked at online. They are also huge in comparison and the major benefit seems to be sleeping capability. While I was searching, I noted that there are small toy haulers as well down to 17 ft. That might be an option.
