Our 5th wheel has the back bedroom for the kids, which is great. But in the main living area, we have found that our seating arrangement needs a re-do. We have one sofa and a dining table w/ four chairs. when the family gathers at night, the sofa is really the only good seating (chairs and table are a tight squeeze). Can we replace the table and chairs with another sofa or some comfy chairs? we end up eating outside anyway, since the dining table is tight and its hard to squeeze into the seats. Where can we purchase matching furniture for our model
