Does anyone Daily drive a K100e anymore?

What’s the wheelbase? Trailer gap will affect your fuel mileage more than anything else with a cabover.

 

The most aerodynamic truck ever built was that fugly 372 Pete. The aerodyne would help with a van/reefer/connie if you keep the gap close. And would hurt with every other trailer

 

Well, not sure I agree. On a 2 lane, when a cabover comes at you, it can throw you off the road, where as, a conventional, not as much. I do think all this aerodynamic baloney maybe gets you another gpm, even the newest trucks still can't muster much over 7, and like I say, I still think it's a conspiracy from the oil companies. Due to the inherent nature of the vehicle, a box, not much can be done.

 

Cabovers have relatively clean air once it comes around the front of the cab. Where the turbulence comes from is the sleeper gap. If you take a truck like a Schneider IH there would barely be any turbulence compared to the exact same truck with another 4ft of trailer gap.

As far as general freight goes, mid-8’s are easily achievable for fleets. I’m at 7.47 lifetime on paper with my current truck. If I had an APU and closed up my trailer gap by 2ft I’d probably be into the 8’s.

 

BJ and The Bear! I don't miss sitting on top of a spring loaded steer axle and would never volunteer to return to such a scenario. Sure is cool to see them still around though.

As for MPGs, it's not always about aerodynamics. A small gutless engine vs a big block makes a difference as much as fueling does. Mechanical pumps vs electronic fuel injection etc etc.

 

Try a 12V71.

 

Ran a 12V71 in an old Astro in NV hauling water to mines. 2.5-3.0 was a good week.

 

Yup. We had one until we could replace it with 3406. Ours pulled an off road low bed or a home-made set of bottom dump triples that never went to town.
We tried to keep track of fuel by figuring gallons per hour but it was too depressing.
The 3406 did a much better job on fuel and power.

 

I dunno. I've seen uglier. I've kind of always been fond of the FL Argosy. I like how the little steps come out to greet you when you open the door, making you feel like you're walking the red carpet.
