If you are asking me - I have a 2012 Ram 3/4 ton pickup with the Cummins 6.7L diesel and a 35 gallon tank,
Depending on several things and with us always staying on paved roads. we get between 10 -13 MPG. So we are good for about 350 - 400 miles. But we always plan our fuel stops at a Flying J so when we get between 1/4 to 1/2 empty, we stop for fuel.
EPA requires gas tanks to have carbon vapor canisters, diesel has no such requirements. There are several companies selling aftermarket under bed oversize diesel tanks, I can't remember a single gas one for something newer then mid 70's.
My 62 gallon under bed Titan tank is good for about 1000-1100 miles empty, 500-550 with the TH. It does go from 1/4 to empty in about 50 miles tho...

All of the above with one addition: I have two filters on my transfer tank. Every drop of diesel that goes into my F250 or my diesel tractor and RTV and home generator goes through those two filters.
It's nice knowing that all my fuel is cleaned of water and particulates before it goes into any of those fuel tanks.
Actually, according to this "Except for diesel fuel tanks, the fittings through which fuel is withdrawn from a fuel tank must be located above the normal level of fuel in the tank when the tank is full. "
Which means that gasoline cannot be used in gravity feed tanks. It can be used in tanks that are pumped from the top.

Here is another BIG reason, in certain parts of the Western US, it is NOT uncommon to drive 100+ miles between ANY place that may have fuel, depending on your flavor,there is not a fuel/gas station every 20 miles or so like the Eastern half of the US and traveling up North is much the same way.
The 50+ gallon bed tank makes a great safety item in that aspect, + the 35 gallon OEM tank and I can choose where and when to fuel up etc.

Transfer Flow makes gasoline tanks. I love the one that looks like a toolchest, but serves both purposes (stash stuff, and 30-40 gallons of dino juice.)

Best answer!
I was born in Great Falls, Mt. My parents moved when I was 5. I found them when I was 10 - they were in California.
