Dinette? What dinette? Where mine used to be in my 30' long no slide Class A was replaced with a built-in 6'-0" long desk with drawers (underneath) on both sides. A very comfortable multi adjustable wheeled office chair now functions as my command center when parked.
It's perfect for me. The desk is about 22" wide so the center aisle is now wider than when the dinette was there giving more space in the kitchen area. Guests now sit on the jackknife sofa or the 360 degree captains chairs. (3 in front) I wouldn't have it any other way. The RV still sleeps 3, . . . . 4 in a pinch.
When I bought the RV used, the previous owner actually discounted the price because there was no dinette/drop down bed.
