Fuel economy

I also have camper and bus and at 85-90 get around 10-12 depending on condition.
As for arerodynamics please read the following.
The idea for the Type 2 is credited to Dutch

For other uses of the word Dutch, see Dutch (disambiguation).

. Volkswagen importer Ben Pon, who drew the first sketches of the van in 1947.
Aerodynamics is a branch of fluid dynamics concerned with the study of gas flows. The solution of an aerodynamic problem normally involves calculating for various properties of the flow, such as velocity, pressure, density, and temperature, as a function of space and time. Understanding the flow pattern makes it possible to calculate or approximate the forces and moments acting on bodies in the flow. This mathematical analysis and empirical approximation form the scientific basis for heavier-than-air flight.
The aerodynamics of the first prototypes were not good but heavy optimisation took place at the wind tunnel of the Technical University of Braunschweig
. The wind tunnel work paid off, as the Type 2 was aerodynamically superior to the Beetle despite its slab-sided shape. Three years later, under the direction of Volkswagen's new CEO Heinz Nordhoff, the first production model left the factory at Wolfsburg
