That means alot Jim. Thanks! I actually thought about offering to bet $250 to anyone who wants to ride along and help with one of my routes. When I win, I'm $250 richer, if I lose, I get a cheap worker, and someone to keep me awake and entertained while driving :D

Nope, but I may try :D My truck is a stick though, which often can account for 5-10% better mileage, so that offsets the tape and mirror trick.

I hand figured a trip to Grand rapids and back in my old 95 cummins, auto4x4 and it figured out at 26.7 mpg and that was at 70 mph. So I have no doubt of 30 mpg in a 2wd stick. I now have a psd and can see how some of you guys that own then are but hurt over mpgs. If you want better mpg buy a 12valve cummins. It is not hard to pull down very good mileage with them. Best empty so far in the psd has been 16.

I have no reason to fudge the numbers, I've posted all my tow rigs in this thread, the good and the bad.
2 wheel drive: check
Well broken in ISB modified for efficiency and not strangled by epa: check
Standard trans: check
Most aerodynamic body of all the bricks on wheels: check
Gearing to keep rpm low: check
Limiting speeds to 65 mph or less: check


If any pickup can hit 30 mpg empty that would be the one. Route55 you said you hand calculate mpg, where do you get your miles traveled from? Has the speedo been calibrated for those tires?

I do, I put 100psi in my tires today, taped off the entire body, lowered the truck 18", taped the gap between the topper and body, removed my mirrors, drafted a semi at 48 mph, and I got 31 mpg today.

One of my worse tanks in awhile. Lots of idling in traffic, and fought a strong crosswind across Indiana. All with loaded trailer. 413.2 miles divided by 23.10 gallons = 17.88 MPG

Brods - in answer to your question, I reset trip odo every fill, and have checked speedo against both my GPS's and they agree. Oh, and my motor is a 12 valve, not ISB (24 valve)

Nope - that's @ 55 mph and no cruise control.

Actual MPG averaged over 2000 mile trip @ Christmas was 15.2 MPG running 65 to 75 MPH.

512,000 miles?

What gear ratio in that? What boost do you see when load and empty load at 55, 65, 70 mph.

Thank

Yes, 512,000 miles. No idea on boost, no boost gauge. Has a boost elbow that is turned up pretty high.

I would like you add boost gauge there so I can know how you got 30 mpg.

My Cousin had I think 03 3500 drw crewcab 4x4 with automatic. He say he get 14-16 mpg at 70 mph but boost were push 10 psi.

My 96 eclb cummins auto tranny 3.55 gears 12 valve pushes about 8psi at 70.

I have never gotten 20mpg, but pretty darn close. Usually gets 18 traveling without a trailer. Gets ~ 13 pulling my 5th wheel camper (28', very heavy and tall)

Only gets 11-12 pulling a 4-place enclosed sled trailer (winter fuel and in a hurry normally).

My superduty has been getting crappy fuel mileage lately. I'm down to 15.5 from around 18. I think its due to more air drag which is caused by the gaping rust holes in the rear fenders.

First full tank since converting to a 3500 dually.

Truck still has 3.55 gears, but is now locked in rear.

No trailer, bed loaded with 12v cummins, 4 bikes, 5 spares, and probably 300 pounds of tools and luggage. Half the miles driven through hills of Southeastern Ohio and West Virginia.



24.36 gallons in 473.7 miles = 19.44 MPG

First half of this tank (with bed still loaded) was through some crazy mountains in the Appalachians (sp?).

Last night I blew out 5th gear, so the rest of the tank was with no overdrive, at 50-60 mph 2000-2200 rpm. The rest of my Florida trip will be with no overdrive!



518.2 miles used 25.62 gallons = 20.22 MPG
