There's no such thing as a permanent tank installation. It's added and it can be subtracted. I bought my tank for my 02 and I traded that truck with the tank in it for the dually. A week later the salesman called that he had a buyer who didn't want the tank was I interested in it. Buyer came over I took it out and had it back and it cost me my labor and a like new HI-Lift jack that I'd bought at a garage sale for $!5. I had another tank I'd bought used and installed in another truck. I sold that truck after taking the tank out and putting it in my brothers truck

We installed a transfer flow 50 gallon auxiliary tank in the bed of our truck.
It’s great, all computer controlled, fill it and go.
With our 42’ fifth wheel no fun trying to get in and out of gas stations.
We installed it ourselves and was easy. Took our time and all together maybe 6 hours but hubby is picky and hide and took time to make it all clean looking.
Some people complain about loosing bedspace but we don’t carry anything in our bed besides the hitch and our truck is only used for towing so for us made no difference.
Also fits perfectly under the bed cover we use.

I added an ATI(Aluminum Tank Indistries) 51 gallon tank to the bed of my truck a while back. I love having the extra fuel as I don't have to stop at JUST truck stops. This gives me a total of 88 gallons of fuel when both are full. It is a gravity fed system and only took about 45 minutes to install. However, I wired in a 12V valve from Valves4projects on Ebay to my upfitter switch so I can choose when I want to add fuel or IF I want to add fuel. Since I already had a toolbox, I wasn't concerned with a bed cover but I did want as much bed space as possible, so my tank is only 9" wide. This is a pic of my setup.

Thanks everyone for the great replies. I am not worried about losing bed space. I have my 5th wheel hitch locked in place. Anyway its to heavy to take out. I won't use the bed for hauling anything. That means I'd have to work, and I don't do that any more.HeHeHe.I like the idea of fueling when I want and probably not having the 5er on the truck. I,m leaning towards a tank 70/90 gal. Grvity flow and I will have it installed. I can't wee well enough to do this kind of work any more.Again, thanks for all the replies. Lots to think about.

I have a question for everyone. I have tried to find a aux tank made to fit in front of the wheel well, against the indentation of the side rails so the tank will not take any bed space, has anyone ever seen such an animal?

Look for a metal fab shop in your area and see what they would charge to make one for you. It certainly isn't a complicated build

My Auxiliary Fuel Tank. Modified! I have only NEEDED to use it once.

"IF" I were to do anything else I would add the 55 gallon TITAN replacement tank.

If bed space is valuable, consider a wheel well, inside the bed fuel tank from Titan, but it is expensive. Snow Performance sells a methanol/water tank for a lot less. Probably others. I doubt anyone wants to make a sidesaddle fuel tank (forward of the wheel well and outside the frame) since the Chevy lawsuit in the 1990's.

Look up side kick fuel tanks.
