What's the best RV/motorhome aerodynamically?

[freebeard]

That's pretty neat, a spiral staircase in a motorhome. Commercial or one-off custom?

They could have cut the slanted side windows to match the angle of the A-pillar, and used a 2nd set of those windshields laid back a bit over the first two. And blistered the A/C.

Oh, and an electric Myers Manx with fold-down windshield and roll bar in the storage bins.

That EAGLE bus might have benefitted more with gearing changes and a solid 6V DETROIT DIESEL rebuild.

The metric is nights aboard over X-miles and Y-years of use . . with all these moho's, come up with those numbers as against a trailed vehicle and space trade-offs and then moho aero might have a starting point.

You all do realize that putting the cart before the horse -- "I want a moho [unexamined assumptions]" -- is where the money disappeared down a hole. Smart Spec trumps Smart Use every time.

Go big or go home, and do it in aero style. Supercar garage included.

What? no smooth wheel covers? No boat tail??

They got me in...second story hot tub...or maybe the garage...the pocket supercar...

I like the toned-down Colani-ness of the nose.

I'd settle for a Cab Over Engine Dodge Ram, fifth-wheel made from a shipping container and an electric Meyers Manx with a folding windshield and roll bar.

UPDATE: I found some interesting Vixen photos, plus a good article.

Speaking of that front end, see how aerodynamic it is underneath? Not only did it have a .29 coefficient of drag, the Vixen was advertised to achieve up to 30mpg on the highway, Phil gets around 28/22 mpg city/highway.

I have known about the smaller Gulfstream Montaj motorhome of a few years ago. Never bothered to read the brochure though.

http://www.gulfstreamcoach.com/Montaj%20layout.pdf

On page 7 (of the pdf, pages aren't actually numbered) is a "Driveability" section. It has some shadow drawings of the Montaj and a typical Class A (like mine). They claim 33% less wind resistance.

No, not earth shattering, and not really very aerodynamic. But on topic here in this thread.

And do I believe the 13 MPG claims? Nope. But it would surely beat my 8 MPG @ 60 MPH. Imagine what it could have done with a more Vixen like shape...

Does this count as a boat tailed RV?

[freebeard]

I wonder what the story is behind that.
