Trailhunter auxiliary gas tank

[Great White North]

After about 4K miles, most of it on HWY driving, I find it quite hard to go more than 14mpg, normally it is below that.
Out West there are long, 75+ stretches of no gas availability and, when I start doing Overlanding I am sure the gas mileage will be around 12.
Does anyone have any ideas on how to retrofit an auxiliary tank, 5 to 10 gallons on these trucks?
Thanks a lot

This is the fuel tank solution that I have been looking at:

Politics do not belong on these forums but avoiding it is difficult.
Most highways have a 75 mph speed limit, and 2-lane rural roads are usually 55mph
The government is 40 years behind on this, and it allows the car companies to publish fallacious gas consumption figures like the Traihunter.
A hybrid is supposed to have good numbers. The Traihunter is not a true hybrid in the sense that its purpose is to increase power in the notoriously underpowered Tacoma line.
But 13 and 14 miles per gallon in a reduced (18 vs 22 gallon capacity) tank is ridiculous.

I'm not trying to argue with you, but I do believe you've identified your problem. You are driving a brick at 75+ mph... and assuming at some point in time you'll encounter a headwind, your truck is going to experience additional wind resistance. You're not driving in a vacuum, trucks (and other larger vehicles) are not aerodynamic.

I totally agree, I understand my driving habits are anathema for good milege BUT, even driving conservatively, like Mr Jesus above, it is way below the advertised mileage.
Yes, it was calculated according to the Gvmt. regs but: IT SUCKS

Thanks, that's what I am looking for here: Ideas on how to solve the problem.
I love the truck, I think it is all I wanted, but I can't run out of fuel in the middle of nowhere.
Again, thanks, it looks good.

I do not doubt your much better mileage, but I am simply unable to drive 12 hours at 63mph average.
I know its stupid, but I just cant, I do 75 to 85, averaging about 70 over long, 680-mile drives, Austin to Raton, NM, for example
You are a cautious, normal driver and I am a crazy one, but a manufacturer should try to produce something fom an average with you in one end and I on the other.
They advertised the Traihunter at 22 or 23 mpg and that is impossible with this truck

Not if your driving the speed limit or 65mph. So the company should build MPG to meet someone speeding over the limit?

65mph is not a realistic US standard for highway driving. Speed limits are 70mph on most highways/interstates of the US and jump up to 80/85mph in some states.

If you're doing 65mph in 99% of the US, you're getting passed.

There are more speed limits at 55mph and 65mph than it is 75mph.

I can tell you from my personal driving habits, speed limits don't mean jack to me...
And from the flow of traffic that I drive daily, seem like the majority of the people are in agreeance with the above statement.

Some speed limits in the United States are 80 mph

The TH was made for overlanding, not highway, so their test speeds are with that in mind. 70 mph offroad is an unreasonable concept. Get a TRD Pro. My TH is loaded with Kuat bed rack, Roofnest RTT, Prinsu RR, loaded Roam boxes and other camping equipment with propane, water, food, lithium batteries, and 18 additional gallons of gas. I'm running heavy. I’m getting 14-18 mpg and unloaded I get 22-24. See photo of instrument cluster panel.

If your worried about running out of gas, travel with Rotopax, jerry cans, or camel bags.

It's obvious, how many people should have bought the Maverick.

That’s awesome

I'm hoping these guys come out with an auxiliary tank soon: https://longrangeamerica.com/waitlist/1741898750869x885361069156728800

not as wide spread as the lower speeds.
