I know this isn't totally related to the thread but it was too cool not to share!!!

I did a search for you on this site using the keywords " 18 wheeler , semi, and rig " but I'm not getting any results. ( confused )
The reason why I did this, is that there are several posts already devoted to this. We have discussed this several times.
Sorry I can't seem to be able to use the search function correctly, but if you search through the 'aerodynamics' part of the forum, you will eventually see several of these postings.

( One thread - mine actually - comes to mind entitled 'Accordian kammback for big rigs ?" It's long dead BTW.)

Good luck

a conventional versus cabover is about as good as it gets...and even then, the only noticable thing, not even fuel mileage, was cross winds are gentler in the long nose (or known as "conventional", beciause conventuional is that obviously "normal", caboivers are a cheat to poor basturds tortured to drive them by capitalism.). It is a case of set power so beyond the quibbling of aerodynamics of vehicles just roaming the earth like giant dinosaurs in superiority..god didn't give a dinosaur a ricer wing either.

I have been around trucking my whole life, and in places that knock a rig over in the wind. Keep your silly areodynamics, and better make it steel. there ius a forward aero of conveneince and comfort, for driver and surrounding machines..the fule? it does so next to nothing through these changes...the aero is for people more than the truck.

You're right.
Brilliant !

On conventional cabs, using Freightliner as an example, they offer a aero and a "classic" body design. Most drivers I know say that with equal trucks the biggest difference they see between the 2 is about 1 mpg and that's in strong (35mph +) Headwinds.

AS far as side skirts etc, I have an uncle whos company spent a couple years carefully evaluating the different systems and they found about zero economy savings vs the cost of maintaining the system. Did not pay for itself at all.

They played with LNG boosted diesel engines as well, and same thing, the maintenance cost overwhelmed the small fuel savings, except when you had a truck who's route was all steep hills, then the power boost of the LNG kicked in and helped the fuel burn on the long 6% rocky mountain grades. But even that simply did not pay.

They also invested in a couple hybrid tractors, and the battery life killed those... They were wearing out the batteries in like 6 months and the trucks needed like 48 batteries at 400 bucks apiece... NO way to make it pay...

Happy AERO-ING

Here's my design for my future reefer cabover 'straight truck.' The box portion will be about 28' to carry a cargo capacity of about a 20-22' footer.

I will test this against a 'conventional-designed' rig. The body will be mounted on a modified roller skate platform.

I'm also going to 'plastic vacuum form' this design for individuals that would like to use it as 'a starting base' for their own ideas.

I'll be updating/uploading photos to Lady Bug Trucking , ladybugtrucking.biz - Registered at Namecheap.com or ladybugtrucking.us - Registered at Namecheap.com

I am friends with a few owner/operators. They want HP in their Freightliners. I asked about side skirts and the answer they gave me was that they get blown around more with the added surface area. They could give a hoot about super singles since it costs money to take off good tires.

Some of these guys treat their trucks like hot rods. They want good looking trucks that go fast.
