Reason behind extra tanks?

[special-K]

All that type of tank/filler are aftermarket. Back East you didn't see these added tanks. It was a Big Western State thing. People cover a lot more ground out there. People had more trucks set up for camping and it was nothing to do a 500 mile (one way) trip for a weekend of few days. Back here it's a big deal to go a couple hundred miles. Gas stations everywhere. My '71 Custom Camper from back east didn't have any extra tanks. I doubt it every left PA till I bought it.

How can it be aftermarket when his SPID shows an aux. tank option? And which xtra tank is "correct"? The driver or Pass. side?
I ask because my 72 Highlander has 2 xtra tanks both with aluminum locking doors. They don't show on the SPID so I assume they are aftermarket but what does the factory xtra tank filler look like? Thanks

You can't see it well because I have a tool carrier over it.
But the left side tank filler goes down the inside of the bed, surrounded by a squared off structure that was painted the same color as the metal bed interior.

The right side tank has the aluminum door halfway down the bed wall, and the tank has a small filler cap inside between the inner and outer fender.

Other than being different ways to fill them, the tanks are the same, that is mirrored to each other.

Even as recently as the 90s I was driving my '69 Pontiac 427 though the northern lakes route of the Trans Canada (the I-90 but north of the Great Lakes more or less) and there were stretches of several hundred miles without fuel at night. My car barely made it, and one of these trucks with a camper would have no shot.

So, they added extra tanks. But there are more fuel stations now.

Pontiac 427? Sounds like you were one short of a 428. Unless you had a Chevy in there

Years ago my father and I would do extended 4WD fishing trips on logging and fire roads in the Cascade mountains. Two extra tanks in that old Ford. Loooog walk back in bear country if you run out of gas.
