1008 cargo cover

[Rich Johnson]

Has any body with a truck that put a cargo cover up noticed how bad it effects the gas mileage on the highway.

In short, I put the cargo cover up first time the same weekend I installed the overdrive on the truck. I monitored my gasmilage religiously and used to get almost 16. Now, on the highway with the OD on, Im getting 13ish because of the cargo cover....(I hope)

So has anybody else figured how bad the cargo cover effects gas mileage?

Sorry but had to say it !!! I never get any GAS millage with mine. But my fuel mileage is about 18 per gal. Sorry! I have heard allot say that about the cover and how it knocks down there mileage. My dad put a faring on his truck to help when he hauls his fifth wheel and left it on while just driving without his fifth wheel and found out the same thing lost about 2 mile's per gallon

Hey Rich, where did you get your cover at anyway?

Thanks,

That doesn't sound right, even with the cover and overdrive. I can get my truck up to 16mpg highway, its 6300lbs turning 42" tires

Whats your elevation?

Rich,

I have a cargo cover on my M1008. The mileage may suffer a small amount but my tools and equipment don't get wet and I like that. A toolbox full of water just don't get it.

It would kill your fuel economy. Take it off and unhook the trailer and take her for a nice long weekend cruise. Check the air pressure in your tires while your at it. Keep us posted.

I got the cover from Walker equipment in Victorville area.

Im afraid that the cargo cover may not be the only reason that my gas milage dropped so far.

Im afraid that even though my RPM dropped quite a bit while Im at 65mph, that maybe the torque required to maintain that speed may be taking more fuel than before. That would be a real serious bummer considering what the over drive costs and takes to install.

I started driving with the cover front and rear curtains rolled up and noticed a serious drop in the resistance I feel in the truck on the highway so I just pray that was it. I will do my milage numbers soon. Not driving much whil Im out on a National Guard op.

I imagine the cover will drop your mileage. A regular cab height fiberglass or metal topper would probably increase your mileage.

You need to have a "Locked up torque convertor" at highway speeds. If you dont then yes you will not get the desired effect you installed the OD for. This can be done. When you get it wired up add a turn off switch to your brake light switch. When you put on your brakes at highway speeds it unlocks your toque convertor so as not to burn it up as you slow down. You may forget if its just an on off switch.
