Difference pulling a V nose and a flat cap

I wonder is there between a V nose trailer , and one like my flagstaff that has a Fiberglas cap on front
My 2012 FR 831 RKSS is around 7200 and I get between 12-10 pulling with my 09 hemi

Do V nose get better mileage, easier to pull??

The 'V' nose trailer sure looks to be much more areodynamic than other trailers. The advantage that I can see is you can still have taller ceilings and maintain a areodynamic front profile.

Other trailers that try to be areodynamic also lower the trailer as well as lower the ceiling.

The Element and Airstream are two areodynamic profile trailers that have lower ceilings also. The Vantage trailer is lower to the ground but keeps the higher ceiling.

It would be interesting to somehow test this. You need the same weight trailers and tow with the same truck.

I would bet the 'V' nose trailer would tow as easy as an Airstream trailer of the same weight. Plus give you tall ceilings.

Aerodynamics is a complex science and intuition is often wrong. For example, the "dimples" on a golf ball are highly helpful but who would predict that from intuition?

From what I understand, the primary benefit of streamlining the front of a trailer is eliminating turbulence from sharp corners, but that only takes modest rounding of the edges, and additional streamlining will have very little effect.

A much larger improvement could be obtained by adding a cone to the rear of the trailer to create an airplane wing-like overall shape, but obviously that's impractical.

I spoke to a fellow that delivers RV's to us up here in Canada at the dealer we bought our unit from. He was from Indiana said he had delivered a few and found maybe 1-2 mpg difference from conventional TT's. So over time it will make some $$$ saving.

Much like a modern submarine -- a blunt (but rounded) nose, and a long, tapered tail (stern?). Or, somewhat like many teardrop campers

I think I read somewhere that a rain drop is very areodynamic so those tear drop trailer like the T@B with the trappered back would reduce turbulance.

So adding the cone to the back of a conventional trailer would work !!! Or an Element Trailer with the back that looks like the front.

The 'V' nose also needs a 'V' butt.

The trucking industry is doing this. They not only put flaps between the wheels of the trailer, but some that make constant cross country long hauls are outfitting all of their trailers with flaps on the very back, which help shape it into a chopped square cone. It's supposed to get them like 1-2 mpg.

I think i saw a video on youtube of someone testing this out. I think he got like an extra 0.5mpg, it wasn't enough of a difference worth trading your trailer in for or spending extra money on.
