Is it possible to add an auxiliary fuel tank behind cab？

Back in the 70’s during the ALCAN pipeline contruction there were a few heavy haul oilfield/ pipeline fleets out of Houston that mounted the extra tanks behind the cabs. Some where on long wb Autocar winch trucks and they mounted between cabs and the winch towers. The tanks had shutoff valves on the bottom and just gravity fed down into the side tanks if/when they needed extra fuel. They would make frequent trips from the Houston ship channel up to Alaska and back. Was and still is legal to do.

 

100% true. I hate donating money to the Government. I won’t even start on employment insurance. FML. What a scam.

 

Thankfully I don't go back east.
Been to Alberta twice in a semi, didn't know that I was supposed to track anything, and didn't.
Interesting to note that we've been audited since, nothing was said.
I do go to the Yukon once or twice a year, just drive as though it was BC, nothing has ever been said to me, or anyone of us that go. I guess occasionally ignorance is bliss.
But I should look it up I guess.
I love doing the trip north that has me cut through the Yukon a bit. Such an easy drive, and a pleasant change. Even kind of fun to just pull over somewhere, build a little fire, cook some dinner, then curl up in the passenger seat of the truck for a sleep.
When I get to Atlin, I do get a room, shower, watch TV, eat in a restaurant, then head back, again having an almost camping like experience for a night. Makes for a great trip, do a little fishing, catch dinner.

 

Exactly.

I would rather owe them, than overpaid all year long.

 

We do keep track of our offroad miles, and get a refund for that fuel burnt. For some drivers it is nill to very little, but for myself it's significant, as I often run more kms offroad than on.

 

Pump price - ifta = buying cheapest NET fuel Cost

 

If you don't care about being stylish you could move to D or square tanks and gain a lot of volume.

The D shaped tanks hold about 45% more per frame rail inch without looking that out of place but you won't find them off the shelf.

 

Interesting, Illinois has the highest ifta of all the states surrounding it, and highest pump price.. But the fuel price, net of taxes is in the lowest 3 in the whole country, so fueling in Illinois, and getting the refund is good business sense.

 

The one that always cracked me up was the Oregon-Idaho line on I-84. Trucks would be lined up to buy fuel in Oregon because it was a nickel cheaper than Idaho. It apparently never occurred to any of them that Oregon had no state fuel tax while Idaho was 20 some odd cents back then.

 

I remember the same thing way back when - guys would try to get to get through Nebraska and buy that cheap Wyoming fuel that was ten cents a gallon cheaper. At that time I think Wyoming's tax was $.14 and Nebraska's was $.27.

One of the advantages of doing all your own paperwork, especially before there were ELDs and GPS gizmos that calculated ifta, was seeing the results when doing the quarterly report.

I had friends that would brag about how much they were saving by driving slow and getting .25 miles per gallon better fuel mileage only to end up with a higher cpm because of chasing "cheap" fuel.
