I guess the designs were better once.
We have a very vintage (soon to qualify as antique) small A. The interior was carefully designed when it was built. We have a dinette and it has served us well. In the time when I used it as a shop for the living I made doing things for keep boat racers, that dinette served me well as center for the consultations with owners, as shop bench for the work on electronic instruments and a place to lay out my computer and papers as was required.
Now that the coach has been converted back to casual use, we use the dinette all the time. It is used during food preparation as it is across from the galley, and then to also partake of said meal and have a face to face discussion.
But then again, this coach was designed by thinking people some of whom were famous interior designers and it was all done near 50 years ago but it still is good today. All those that have remodeled these coaches gave up some function to do it.
