Thank you everyone for your great suggestions and information. I will pass them along.
A few considerations I failed to mention is that my brother is 6-ft 4-in, so interior height is important. Also, almost 100% of our "family camping" is dry and in the boondocks, so fresh water capacity is important. I also noticed that many of the smaller Class A's have tiny kitchen areas with two-burner stove tops and a dinky sink. We cook like crazy when we camp and that just ain't gonna cut it.
But you have given us plenty to research and I appreciate, as always, this forum's generous assistance.
