We'll be embarking on a long trip soon and I think it's finally time to bite the bullet and add a second fuel tank. We usually travel solo, but our travel buddy for this upcoming trip has 60 gal capacity for his truck. I don't want to slow him down with twice as many fuel stops as he needs, but he's also got a bum prostate and needs to stop often for biological reasons. These two "needs" might balance out, but I don't want to be the limiting factor for this lengthy trip.

Anyway...

I'm looking for suggestions for a second fuel tank for my pickup. I assume the best option is a thin vertical tank in the bed of the truck, but I don't know much about this yet.

When I was a kid we used to take a lot of trips down to Mulege (Baja California) and the Mexican gas was so horrible that my dad added two aux tanks to our truck. The problem was that we had tanks 1-2-3 and a gauge switch that showed A-B-C. Dad knew how the tanks worked, but I wish I had a dollar for every time my mom "ran out of gas" on the boulevard because she saw an F on the gauge but she accidentally had the wrong tank on the switch and ran us out in front of McDonalds (again). (It was even MORE embarrassing because the McDonalds was about 30 yards kitty-corner to dad's fire station and one of his crew would eventually drive out on a run and see us stalled in lanes.)

Again, anyway...

I'm looking for a cheap and easy fuel solution so we can make it further than the 200 or so miles that our current tank affords us.
 
Dave,

I went with one of the Titan XL replacement tanks. Took my capacity to 50 gal. I little more expensive than a single tank but works well.
 
I can't help you with cheap, but can easy.
I purchased a RDS brand (made in the USA) from marketplace. I think around $500.00. I like it because it has a tool box on top. Fuel capacity is 40 gallon, truck holds 30. It came with all wiring, hoses, adapter, and pump. I mounted the fuel guage and pump switch in the console with a homemade bracket. I can refuel while traveling without stopping.
 
RDS 50 gal with toolbox on top. Got the std pump with hose/nozzle; need to stop to stretch add anyway; so, fuel on side roads. Easy install, useful and great addition.
 
I also have the Titan replacement fuel tank and really like it. Thing I like most was the ease of install and not have to deal with auxiliary pumps or connections. It is even possible to reprogram you fuel gauge to the new capacity but I think the limit on that is 55 gallons, close enough for me though.
 
Tractor Supply "L" shaped 90 gal fuel tank in front of and under crossover tool box plus a 12 volt fuel pump. Inexpensive and gives great range. My F350 fuel tank will outlast my bladder so I just top off fuel at rest stops or lunch break. Great for fueling my tractor and can be moved to a new truck one day.
 
When I had my 2018 3500 ram I had a 55 gals installed I love it, but I traded it in for a 3500 Ram LB which had a 50 gals tank in it, bummer I spend a lot of money upgrading my 2018.
 
I installed a Transflow 50 gal in bed tank. It gives me a total of 82 gal. Once the fuel gauge hits a half of tank the pump on the aux tank goes on and transfers about 5-8 gal into the Oem. The in bed tank also fits under my bak flip bed cover

I used 4 - 5 gallon cans with hose extensions before I put in my Titan tank. I love the electric pump for refilling while on the road. In fact I try to keep the main tank full all the time now. It fits perfectly in my 2017 Ram 3500 DRW.

I have a 60 gallon tank in my box that is gravity feed into my main tank. When my fuel gage starts to move, I know my 60 gallon tank is empty. When I am towing our 5th wheel, I need to get fuel every 700 miles or so.

I put on a 60 gallon tool box style. Sits flush to the bed rails and fills the area in front of the fifth wheel. I run all day, then when we stop for the night I disconnect at the campsite and go fill up for the next leg. Our mid day stops are more flexible without the need for fuel.
 
Long story short, had a short bed, 32 gal - added tranferflow 40 gal. New . truck, kept the reserve tank. Now a long bed with roll back cover and the tank. OEM tank is 55 gal. now I fuel at my convenience. Transfer Flow is more expensive but VERY convenient. Had it wired to mu AUX switch so I can choose when to let if function.

We have a 75 gallon in bed tank from Transferflow. The tank takes care of it's self. It fills the factory tank as needed. Very easy. I can tow my 3791RD over 1000 miles between fill ups. The thing is, I buy fuel when I want to and the price is right. I never run low. They sell several different sizes. But my Chevy 3500 DRW diesel can handle the extra weight.

We bought the 50 gallon Transfer Flow in Rico, CA and had it installed there. Would not be without it.
