WRONG......a vee nose trailer was designed for better mileage, ask any CDL driver -

Dan you are right to a degree. Its based on the height of your vehicle. If your vehicle is as tall as the trailer than it won't make a huge difference. But if your trailer is taller it will make an extreme difference!

All I was saying is mine with a v and a slope nose still got crappy mpg. But yes if the trailer was alot higher than the roof of the truck I bet it would help.
Also, some of these v-noses on these trailers are not very deep. It's still like pulling a billboard. |

All other things being equal, I have to think a v-nose is going to be more fuel efficient than a flat nose.
I don't have any fantasy of it making a major difference, but a 5 - 10 percent improvement? I hope so. |

The thing is those little "wedge nose" style won't make much off a difference at all,, if it's a 45 degree v front it makes more of a difference.
What guys fail to factor in is surface drag,, the more surface area you have adds to the drag also. So what you win with angle deflection is somewhat lost with added surface area. Just put a flag out the window of your car,, it has zero angle, but sure does grab the wind, doesn't it. |

My Avalanche gets about 17 miles to the gallon on the highway without the trailer... and about 8 with it. It's a very light 6x12 with a V-nose.
I think the cars and trucks today are made for highway mileage. If you put a load on them, or switch to trailering mode which shifts the transmission at higher RPM's, you can kiss the gas mileage goodbye. |

This is true for 1/2 ton chassis' and cars,, my 2500hd with the 8.1/Allison gets 10 whether it's empty or hauling a 10k trailer. Speed plays a big role too,, you try getting all that drag going over 65-70 your mileage tanks even more

A V-nose will make a difference to a point. It still nees to "displace" the atmosphere, and it can only do so much before it makes zero difference because much like a displacement hull on a ship, it can only move so much water so fast before the water pushes back on the hull...regardless of how much horsepower you are pushing it with. That is why a planing hull was developed. It skips aross the top of the water. That is how they get the speed. So, a better design would be a more rounded, aerodynamic nose for a trailer, instead of v-nose.

On long trips , I place a roof carrier on the roof of my Suburban ..it will make a huge difference in mileage ..

The high gear (used to be called overdrive) in today's transmissions is designed to keep the motor turning very slow, but keep the car moving as fast as possible. The result is good gas mileage, but no torque or power. So, if you're pulling a trailer, your car/truck is probably not running in the highest gear at highway speeds, and if it is, it's dropping out of high gear every time you go up a slight incline.
Until December of last year, I had a Porsche Cayenne... 400HP, and it still got 26mpg on the highway. But if you were in high gear and tried to pass someine, it had to drop down from 8th to 6th or 4th gear before you could really take advantage of the motor's torque. It would easily do 60 in second gear, so it wasn't a problem... I guess that's why they put those sillly shift paddles on the steering wheel, just 3 clicks and you've got all the power you want... sure is different than when the accelerator pedal was actually connected to a big 4-barrel! |

V nose helps, but the really big help is a V tail.
