Aerodynamics vs. Appearance

Yeah no kidding

 

Actually it comes down to physics.
Making a truck have higher drag and resistance doesn't increase fuel economy. Most of the old hood trucks lived at 4.5-6mpg range. Few did 7 , let alone 8+ mpg on any regular basis.

Obviously cost is a factor but being a idiot with aerodynamics these days is just fuel consumption stupidity. I'm not arguing that the classic look, looks cool.

 

Boy if only ran 200 miles a day I'd go after looks a whole lot more than I have.

SO MUCH FOREHEAD

lol. I'd just rock a flat top with a folding panel. We had one on the old Prostar but it was rusted into position. I believe they were supposed to be adjustable.

If you really want to be pimp find a shop that will hook up a pneumatic piston so that when you hit the highway you can flick a dash switch and the thing will raise up.

But yeah, under 45 it isn't going o make a difference.

 

How is a Wabasto parking heater and an electric Apu going to save money in a day cab?

 

Aerodynamics mainly come into play above 55 for a truck. The high drag of the conestoga sytem is going to negate any aero upgrades for his operation.

 

Shutting off the truck at the docks or on break everyday.
Yes, they do make systems for day cabs.

 

Close enough anyway, above 50 mph the drag becomes exponential and can represent huge economy losses.
Does the truck stay under 50 mph while doing the 300 mile daily routine?

 

Clearly your continued flogging of this horse shows that you didn't read the original post and if you did, you are unfamiliar with this type of operation.
1) Conestoga is a permanent tarping system for flatbeds. Most often it is used with metal loads. These loads are unload most often inside, by crane. You get out of the truck to secure or unsecure the load, unlike a dryvan bumping a dock and sitting there for hours. In a daycab there is less benefit to these anti-idle devices when you are outside.
2) The OP said they do 100 miles local and 200 miles on the road, which means 100 miles one way. Although, depending where the OP is, there are plenty of opportunities to hit highway speed, the amount of time at 55 or faster is small.
3) Based on the mileage the OP is getting, stop and go fits nicely. High percent at highway speed does not. Why do you have a hard time accepting this?

 

Facepalm.
Over half of the OP's daily operation....2/3 actually are AT HIGHWAY SPEEDS.

I'll take conestoga any day over regular flatbed with a high drag load.

Thanks for the explanation...preaching though.....I'm sure you reached someone who doesn't know and it sure as hell isn't me.
