Cherokee greywolf front cap. Vs salem cruise lite front cap

[MWalker]

Just wanted to know if the smoother more rounded shape of the greywolf will help the MPG vs the more square cap on the Salem.

Also if anybody know if the cabinet and seats are made of OSB or plywood. Thanks for your input.

Manufacturers claim the smoother front caps, and more aerodynamic shaped fiberglass caps reduce wind resistance and therefore improve MPG. Most anecdotal evidence suggests that any improvement is most likely not significant, if even measurable.

But they do look much better and are less likely to dent from contact with normal road debris.

Actually mythbusters debunked a myth similar to this.
Round smooth golf ball didn't go as far as a dimpled golf ball. Dimpled ball was more aero dynamic.
To take it further they did the same thing to a car to test fuel mileage.
The car that looked like a golf ball via hundreds of pounds of clay and dimpled got better fuel mileage then the same car that was smooth.

I boat will go slower on smooth as glass water than a boat on the same water with chop.
