Aeromodding a 2021 Freightliner Cascadia
 

6 weeks ago a signed a lease to drive a truck pulling reefer trailers cross country. They pay a certain number per load for fuel, it I use more, it comes out of the pay line. If I use less it goes in my pocket

So here we are. I can't do too much crazy stuff but considering the 2023 is available with aerox package a la carte, I may buy some factory pieces, I may build my own.

So far I've been eyeballing the bumper extension/airdam but they seem susceptible to damage, wheel well filler trim pieces and my 10" side skirt extensions.


So far, I've found stated numbers of .25% efficiency increase with commercially available wheel covers for the rear. If my truck seems to average 8 mpg loaded, that doesn't seem enough for what they cost. Diy in process

Sorry I haven't been updating, although I have been at it. See updated photos.

My latest idea is to build a quick attach trailer tail. That's what the sketch with the measurements is for. I believe most of the trailers will have hinges in the same place so I'm considering a mount to them.

I thought about wheel covers for them as well but I'm sure I would forget them and the first time I have to drive back to get them it would negate any savings I may have from utilizing them.

Man, I'd get pretty crazy AB testing if I got to pocket the fuel savings.

Guess you won't be going in this direction

Welcome to the forum.

Welcome.

Do you know how to search the forum? It goes pretty deep.

Do you control the trailer, or are they rotated out? Here's something that relates to your use case:

Red, unfortunately I'm not a scientist, I'm not cool enough because I have a plastic bumper and a robot shifting gears for me

Free beard I've been lurking for 8-10 years. I'm pretty familiar with site functions thanks. Unfortunately I can have the same trailer for a few days or even weeks but the hope is to drop and hook at every stop. I have a sliding fifth wheel which I was hoping to slide all the way forward but weights do not permit.

All of the trailers have skirts and super single tires, some have 4 sided trailer tails, some have two sides but they're skirt always broken. The new trailers seem to have a two inch treatment along the lower middle of the door and a5 inch spoiler along the top and sides. I'll try to get some photos

Got it. Lurkers are important.

I don't care enough to search but there were wheel disks that expand like a crochet hoop to grip the wheel. Maybe they could be moved from one trailer to the next.

Probably an old hat to you, but Vekke designed smooth hubcaps for trucks/trailers some 11 years ago.
this is his thread: https://ecomodder.com/forum/showthre...cks-16478.html

and these YouTube videos seem to be most informative:

Covers are made of 3mm ABS sheet, iirc. The design is pretty straighforward, so you should be able to duplicate it, unless you are hopeless with jigsaw. I would try it for sure, if I were in youe shoes. smooth hubcaps are how much? 3 %?

Not the same one [IIRC] but just as good. :thumbup:

A good tire pressure gauge and a long enough air hose to reach the trailer wheels. Properly inflated tires make a big difference when hauling heavy.

Oh, and a scangauge.

Seifrob, thank you for the link and videos. Looks like I'm going to buy a jig saw.

Redneck, I have a gauge. I need to buy a hose and adapter.

Thanks for the ideas folks, keep them coming.

I'm looking at extending the side fairings and an air Dam/splitter.
