Don't want to loose any space, love my bed height HighwayProducts 30" deep tool box.

A few cents a gallon here and there, I am past trying to save every penny.

I have to assume you have a short bed, a few cents? Last fill 48.7 gallons @ $1.44 with discount card savings $46.67, last few 20.86, 43.94, 25.86, 40.41 in savings with 5 fills. I'll take the few cents about $150 every day. Truck tank + the 80 gal transfer tank that's switched via up fitter switch in the cab, truck on, up fitter switch on, tanks switch outside on, pump till full.

I don't think those savings add up quite that fast. You need to recover the cost of the tank and installation before any savings begins. Next you need to consider you spent an extra 115.00 in fuel to keep your aux tank full. At some point you are buying and storing fuel you don't need.
I don't dispute that there are savings to be had, but it's not as cut and dry as it my seem.

To me the best advantage is being able to fuel when I want to, not when I need. Too many times a head wind cut mileage and I needed fuel now in an area I don't know. Where can I get fuel in some little town? I can pass through WA or CA and not have to pay outrageous prices. For a weekender with a two week vacation it's probably not worth it. Being about 3/4 time the convenience is worth the cost. The savings is an added benefit. Don't understand storing fuel I don't need. Unless I plan to sell the truck or stop driving it is going to need fuel & in that case the tank will be drained for transfer to the next truck.

I agree it more about convenience than savings. I also agree there is savings to be had by avoiding higher priced fuel.
However you are carrying 80 additional gallons that may not be necessary. Would you save even more if you had 2 tanks? Are you spending more or saving more? There is a return on investment factor to consider. There is $115.00 additional dollars in the truck stops pocket that is not in your pocket.
I have a small aux tank that provides some savings and convenience
but I spend more when I fill the aux tank and I don't always use/need the additional fuel. I think sometimes the fuel station wins!

^Ha, right?
He’s posted a pic of that stupid gas can more times than I can count on both hands. Seems every time there’s a slip tank thread.....which is one of the top 20 redundant threads on this forum I think.

12V. Honestly I’m surprised you actually claim that pic is yours considering it’s a cheap, unsafe, hard to pour, Chinese fuel jug!
I’d really expect that you’d be rockin a nice USA made steel Eagle can or a VP race jug or something that is closer to your otherwise discerning standards.
Rofl.

But says something about someone who’d rather stop at a truck stop every couple hours to take a leak than stop in more pleasant places.

LOL, and there it is. OP already says that an extra 9 gallons makes no difference, but let's post a photo of a 5 gallon jug anyway..........

The only quirk I have had is that twice in the time that I have owned the truck, the valve got gummed up and stuck closed and wouldn't allow the tank to drain. It only took about 15 minutes to get under the truck, take it apart, clean, and reinstall, but it could have been bad had I run the OEM tank all the way down and planned to continue driving through the desert running on the aux tank.

Also happened to me once few years ago. I always leave my valve open now and no issues since.

Fuel weighs a lot. It is highly flammable and can combust on impact.

My Ford comes with a 35 gallon tank and gets better mileage than most tow vehicles. I rarely ever feel short on fuel even traveling in the outback of Nevada which is some of the loneliest country in the Lower 48.

I put in a 60 gallon RDS aux tank when I bought my truck back in 2011. I have around 95 gallons of overall capacity, and I agree with what many others have said about it being one of the best upgrades I have done.

Mine is gravity fed. I can open the valve when the OEM tank is full, and the fuel gauge won't drop until I've run all 60 (actually seems to hold closer to 56) gallons are gone and the OEM tank level starts to drop.

If you look at the dimensions of the tanks, there doesn't seem to be much difference in physical size between the smaller tanks and the 60, so I wouldn't go any smaller.
