V-nose trailer owners

Does a v-nose trailer actually give you better gas milage? I have been trying to get an answer on this for a while but, either the owner has changed tow vehicles with the 2 different trailers, or the trailers were different sizes.

See but even in there, alot of speculation, and no one who has pulled both with the same truck and same size trailer. Abtech makes a good point that semis would be utilizing them if they were better. But semis use skirts to help the trailer draft off of the truck. With a pickup pulling a enclosed trailer, the trailer is not drafting off the truck.

Yep... It's open for more discussion. I just remembered asking that same thing, and remembered that previous discussion buried in another thread.

Semi's can't afford the extra space that a V-nose would require. And they have those cowls on top (most of the time) that completes the "slipstream". There's no need to a semi trailer to have a v-nose to cut the air...

I think it would be more aerodynamic with the V on the back of the trailer. That's where the (fuel sucking) turbulence comes from.

I considered putting one of those semi-bumps on the bottom of my trailer door (won't interfere with ramp operation on the bottom) and see what it did for mileage

+1 to Frenchy.

The front gives a better Cd, but more x-sectional area. The focus should be on the rear for milage.

They can put ramps into the v-nose, so just make a double v-nose with ramps on both ends.

Optionally you could also treat the sides to reduce the drag.

I would be curious about the added efficency with a streamlined trailer, with the ass end tapering to a nice point like the cone they put on the tail end of the space shuttle. Practial problems is alot of added length of unusable space. But a big 8' diameter Airstream looking trailer shaped like the belly drop tank of a P-38 would be very cool

Unusable space? Hell no. Put a rack in there for the beer.
