Which RV have the best aerodynamics? A, B or C?

None of the above.

A teardrop has the best aerodynamics but probably the least amenities.

It really doesn't matter unless you are towing 50,000 miles a year. Have you seen a semi tractor-trailer? If the aerodynamics could be improved, they would do it. A difference of 1 MPG makes a difference when you travel 50,000-60,000 miles a year. For the typical RVer aerodynamics aren't worth talking about.

Plus reduce your picture to the forum maximum width of 640 so we don't need side by side monitors to view one picture.

Your best bet is to get the TT you want and forget about MPG.

Hi,

Class C is the worst from an aerodynamic point of view.

How deep are your pockets?

He / she is asking opinions based on the three units posted, not which class RV. Probably should have numbered instead of using letter designations. Then, again, she/he did post in the Travel Trailers forum, so obviously...

From the three choices above, I'd say the best aerodynamically designed one is the first, so, A.
BUT, the differences in the three units are negligible.

They did some pretty extensive research on all the different front ends on horse trailers and found the 'only' one that made a difference was the "V" nose. Which sadly the RV industry does not offer.

An air dam on the back of the TV would lift the air and prevent drag improve handling. Horse people use them a lot. They DO make a difference.

I am surprised that you don't see more RV'ers using them and/or see them readily advertised for RV's.

Here is one RV'ers experience adding an air deflector, pixs, specs, gas savings, drag etc. Pretty interesting.

It is what it is...

The comment about putting the air back after ripping it apart about sums it up. You never see a square tail section on an airplane.

Without exact dimensions, the question can't be answered.

Frontal AREA is the thing that matters, especially with such similar units.

Frontal are is about the same on all of them (including the Airstream) so they're all pretty much the same....

Doesn't matter much; its about frontal area and they are all rolling bill boards. Weight is more crucial and HP. More HP used equals more $$$.

Important question is
"Can you afford an RV?'

Fuel consumption is not the most expensive part of RVing.
