My 2012 F350 crewcab DRW has a 37-gallon fuel tank. Apparently, the OP has a short bed SRW truck. Adding more fuel capacity to the truck will also increase the weight of the truck and decrease the capacity he can carry on in the bed.
Before adding any additional fuel capacity, weigh the truck and trailer to see how much room you have for the fuel weight.

Amen to that.
In my youth, I ran out and got the largest aux tank I could find and dropped it in the bed of a Chevy 2500 Duramax crew cab long bed. No thoughts as to what a 200 gallon tank of diesel would mean to me other than the fact that I could drive to the moon and back.
I was eager to fill it up so I did on the way home and saw what that did to the suspension and handing. Then I penciled it out and saw that 200 gallons of diesel was 1,420 pounds, not counting the weight of the tank, and that this was probably "a bit much"..

I added a 60 gal. aux. diesel fuel tank and this did affect my milage. My 3500 Dodge truck pulls a 14K 5th wheel and it pulls with no problems after instaling the 60 gal. tank.

Did you check the gross weight of the truck and the rear axle weight after adding the 60 gallon fuel tank full of fuel and carrying the pin weight of the trailer.
One gallon of diesel fuel weighs about 7 lb. So 60 gallons will weigh about 420 lbs plus the tank. Add you loaded pin weight, cargo, etc, are you still under the rear axle GAWR?

Lol. Who cares if the OP has 20 gallons or 26 gallons capacity? Either way, that isn’t nearly enough.
Check the Titan replacement tank of the RDS auxiliary tank. I have an RDS 60 gallon. I don’t have a tonneau cover but if I did, it would still work.
The auxiliary tank is one of my favorite things of my truck. Works great.

Here's my opinion: On these newer Trucks with all the HP and Torque a few hundred pounds of extra fuel will never be noticeable in the mileage. It take thousands of pounds of weight to make a difference and even that isn't as much as the frontal area of these Boxes we pull around. My first Diesel a 2005 Chevy Duramax with the 5 speed xmission was used to pull three different trailers, a 24' TT, 30' TT, and a 35' Fifthwheel and the mileage towing was so close you couldn't really tell any real difference.

I was looking at the Titan tanks a number of years ago. My '02 D'max has 26 gal and the replacement is 45 or 46 gal. Can't remember for sure. I do carry a 5 gal can in the bed as a spare, but I just plan for my range. Hell, at a certain age, you've got to stop every 3 hours to pee, so just find a place to fill up. If DW's with you, it's usually every hour. :-) I know that, on my way to Colorado, I have certain stops, and that includes the rest area / tourist office just E of the AZ border on 40. We go in, pee and I dump the 5 gals in, and I can make it all the way to Gallup, after topping off in Payson AZ. Just refill the jug when I stop in Gallup. Because I almost never travel alone, I really don't need the larger tank. Yeah, it'd help me find cheaper fuel and bypass more expensive areas, but it's not that big a deal. If I needed to, I'd bring 2 5 gal jugs...just in case.

Agree %100 based on my own milage after installing a 60 gal. Transfer Flow auxiliary diesel fuel tank.
