Deleted inserted photos because they are not working please see attached.
31.07MPG has been achieved with this at highway speeds!
The truck is 9300lbs!

It runs a compound turbo set up and has other performance modifications to the engine as well as a programmable tuner.
He has a 6x8” lowered suspension and a 3” body drop.
The MPG is mostly thanks to the six speed conversion with a .61 final drive from the transmission and 3.42 ring and pinion ratio. That is cruising 70MPH at 1600RPM!
The truck owner also pulls a 53’ enclosed trailer with two cars inside. I don’t know the MPG with it in tow.

The truck weighs 4183lbs (a Honda Civic and then some) more than mine does at 5177lbs!
I will be performing many of the same modifications.

Take the energy required to move that amount of weight. Hypothetically if it being 1/3 the weight made it capable of 3 times the MPG it would be a 3100lb vehicle that gets 93.21MPG. That’s about 50% more efficient than your Honda.

The fact is I need a truck; a truck that can that can haul. It is the right tool for the job.

My beliefs probably differ from most of the people on this forum. I will refrain from expressing those here and hope we can respectfully disagree. The tread is a work in progress and you will see sketches or actual forms as it continues. Please note the Fleetline photos in the first post.
