Great tank!!!
Xterminator✓ Verified PurchaseJuly 25, 2023
I have 0 complaints after installing in my truck. Looks good ordered on Sunday it arrived on Tuesday well before the actual delivery date, which was a nice surprise. Mine did come with 0 packaging and covered in dust. But it was completely undamaged and the dust wiped right off. Has a nice locking car on top, and came with 2 keys. In my 2007 Ford f350 I have 0 issues seeing my 5th wheel hitch, fact outside of the cap I can't see the top of the tank at all. Make sure you use the accompanying bolts and springs. You might ask as I did why the springs? Hard bolting this aluminum tank down with the movement and minor sloshing will bust the welds on the tank, it's has to be able to move some. Also make sure you DON'T bolt to the frame, in an accident could cause the tank to separate from the truck.
Great Quality!!!

Construction is from a single sheet of aluminum welded at the top and welds for the side ends. Less point of failures. Easy to install. They included the bolts with spring for flexibility and enough strip of rubber for under the tank for friction. Very sturdy and well designed.
I already had one custom made about 8 years ago. It was made all the way to the fifth wheel bracket so eventually the weld got damage and it started leaking. I look around and settle for this model. Is the same shape as my old one but 4 inch shorter in width so is doesn't reach the bracket this time. This vehicles are not the most fuel efficient when towing so the extra fuel is a must for long trips. At 63 extra gallons I'm setting at around 87 gallons of fuel which translates to about 1K miles.

Will definitely recommend for anyone who wants the extra mileage during trips.
Great investment

Best investment if you drive any distance. I do hotshot loads with a 46ft flat bed trailer behind a f-350 dually it's not easy getting fuel any where and I can pick and choose where to get fuel now with out worrying about running out. Liked it so much I purchased another for my everyday truck.
Easy to install yourself.

It took me about 3 hours to install it by myself. Could have done it in half that time but I had to clean a lot of road grime off around fill tube on my truck before cutting it open. It was super easy to install and was a perfect fit in my 2015 Ram 3500. The top of the tank sits flush with the top of my bed rails. The filler cap and vent do stick up above the bed rails about 2.5 inches. From the drivers seat I cannot see the tank which is perfect for hitching up my 5th wheel.
Solidly built tank.

Quick shipping. No box but no damage and seems really solid. Super easy installation, took me about an hour by myself. Also it has a locking fuel cap....I don't recall seeing that in the description.

FYI, this is mounted in a 2018 Ram 3500 dually.
