I'm curious as well how other people are doing? Has anybody had a fuel economy difference of trailer width vs height? My hopper is 96 wide 84 sidewalls. Sticks about 6inches above the sleeper. Wondering if 102 x 78 would pull easier? On the 6 days a year that the weather is nice I can get 5.5 at 88 to 90k

My personal truck and trailer 2000 studio kw with a modified 6nz.
Trailer 13.6 x 102 x 48 walking floor exterior rib.
Loaded 75 mph 4.5 avg.3.8 in bad wind. We run mostly in mtn terrain.
If i run mt very far i lift frt axle. If there isn't to much wind i can get 6 -6.5
Up hill, wind, whatever my mph doesn't drop much.
I can pass most everything but a fuel pump.

94 flat top w900L 44k rears 13 speed 3406e CAT with 750hp tune and stock turbo pulling a 48' flatbed and/or a 102x40x66 I average about 5-5.5mpg usually doing the speed limit or 5 below.

you're the one in 88 to 90000 pounds is 4,5 tons more than your normal 80,000 pounds count again to the 6-inch different than your height really insignificant ber with I would say actually hurt you being that your truck would be some type of aerodynamic truck no matter what it would help with a wider trailer you get better mileage yes but your main problem is South Dakota is the winds and the terrain the lack of trees to break the wind that is the problem

If you're going west or north The Windsor always harder on any truck no matter how aerodynamic are the trailer or whatever even if a interstate system is concrete compared to asphalt concrete you get less fuel mileage because of the way the concrete is placed compared to the asphalt all those little things sound insignificant but they do make a difference and your overall mileage for fuel on your truck your tire tread all that stuff makes a difference

I would be very happy with 6 miles per gallon. My last tank was 5.4 miles per gallon at 88000 pounds heading from North Dakota to Minneapolis with a tail wind and staying around 63 miles per hour. In heavy winds driving conservatively I only do about 4.75 miles per gallon. I Run a B model cat With an after market Bullseye Turbo and Advance timing and stock settings on the rack. Factory boost is 19 PSI at 1400 rpm and 21 psi at 2100. I now get 36 psi at 1400 rpm and 31 psi at 2100. My EGT is lower than stock with the increased air flow. I have 3.58 rears, 22.5 talls, and a .86 single O.D. 13 speed. I try to always cruise at under 15 psi and I never use full throttle except when I'm in the top hole and only when absolutely necessary to maintain my speed and a steep grade. I have only put 9000 miles on with this current set up so I may not totally have it figured out.

Did that, still about the same mileage. Did find the 102 was annoying at older feed mills. Ran into some places where 102" was not allowed. Now 50X78X96 Timpte with big doors. Ground cleanance kinda tight, but seems to be working ok, and can haul the same. 67200 with half tank fuel. Except Hulls. 5 and change, 7 axle 96,000 gross.

It would be VERY hard to average over 6mpg with a hopper. Just to much drag with the hoppers hanging down.

My best MPG truck is a 99 w9 with a N14 and 3.55 gears, getting 6.2 mpg on ifta reports normally.

Worst is a Volvo with d12 motor.

We run mostly two lane roads in the upper Midwest.

In my opinion, which everyone has, in order to get good mileage pulling the hopper you need big horsepower the correct rear ends and keep your foot out of the damn thing.

6.5-7 mpg is not hard to get

05 t600 with twins. And autoshift 18 sp

it will always get at least 6mpg but that is always at 55-60 mph. If I push 65-70 it is 5.4-5.7. It has 370 gears and double over

has no issues with power it is always loaded at 96000 Flatbed to kanas with 80000 gross it got 7.64 in the summer.

Now a person seems to run harder just to get the extra load in.

The trucks sit if they don’t get .14 per ton per mile. I have shippers who did have trucks and sold them because of expenses and failed drug tests.

The trucking business is going to get tough in the near future with the drive yourself truck and the 5g that is coming out that is used to track everything drones are taking over

in Minot Nd there is a central hub that unloads all the cube vans and ships them all over. They are building a 320 acre facility with rail and drop off already they also had and still have a brainstorm about self delivery

I am running my 06 isx deleted and tuned to 580hp. 13 speed with 3.58 rears with low pro 24.5 tires . My trailers will make you cringe. My hopper is a timpte 43ft 102 by 102 and its 13ft 4in high. My walking floor is a 48 ft wilkens closed tandem sheet and post. I run permits grossing up to 95k about75 percent of the time. My ifta quarter are between 5.2 and 5.8. For how i abuse the truck i can't complain
