Poly or steel replacement fuel tank?

Looking at replacing the stock 25 gallon fuel tank on my 2015 F-350 SCrew short bed with a larger 50 gallon. There appears to be two good options available. Transfer Flow provides a 50 gallon replacement made of aluminized steel for $910. Titan offers the same size made of polyethylene for $1410. Both are mid-ship, include all necessary hardware and don't require removing the spare tire. I live in Oregon where the use of salt on the roads is not allowed. Opinions on which would be the better way to go?

2015 F-350 SCrew 4X4; 6.7 L; SRW; 6 3/4'; 3.55; 11500# package

I don't see much difference in either functionality or longevity. You might just a well go with the cheaper option.

Transfer Flow has had an excellent reputation for quality products for years. Titan is relatively the new kid on the block. Plus Transfer Flow has factory-approved installers all over the USA. I don't know about Titan. And Birder should know, Transfer Flow has excellent, proven electronic interfaces between their tanks and the Ford instruments and gauges.

I have the Titan tank and chose it because it weighs far less. I saw your prices and then looked it up, they have increased considerably. Unless you do serious off-road, there is no need for the shield. Shop around and you can find discounts.

I chose to replace my 25-gallon tank with the Ford OEM 36-gallon tank that was standard on the 2012 4x4s. That cost more than the Transfer Flow, but I'm glad I have it.

With my stock tank, I had to look for a gas station at around 200 miles when towing. With the 36-gallon tank, I don't need to start looking for a Flying J until after 300 miles towing, and well over 500 miles when unloaded.

The 36-gallon tank is now optional on all new F-150s. That's an option you don't want to omit.
