The rear shape was an attempt to streamline. Just as the semi's now are long nosed. The problem is, it takes up living space so the flat, bus, front gets the nod now-a-days. More space per foot of length.

As far as I can tell all of the companies have now moved to a more vertical front end.
Anyone care to comment?
The rearward slope of the front end IS "Frontal Area."
Reportedly, this design element is the largest area for improvement for Drag Coefficient.

The BEST front end design for MPG efficiency would be a VERY sloped front end, the top and side corners should be a rounded as possible, and there should be an air-dam of some sort. This was reported to contribute as much as 80% of the Drag Coefficient on a CabOver OTR Truck (similar shape as a bus style RV).

For a Class "A" RV, the space loss in the interior from this shape is only the front overhead cabinettes (unless there's a drop-down bunk), which shows how much customer visual preference is the controlling factor.

There are exceptions, like the Monaco Vesta.

I would bet the reason for the "flat" front is the same reason the cab over semi tractor was popular years ago.... Length laws. When the law was changed for big trucks conventionals became popular.
The coach builders are limited to 45' and to maximize living space and the bus like front end does that.
