I had one on my 2011 f350 srw diesel before I sold it last week. It was awesome! Stock tank was 26 gallons. Titan tank was 48! I installed it myself. Instructions say 3-4 hr install time, but I took 8+ hours. It didn't hang down from the frame anymore than a couple inches more than stock tank. Not noticeable at all on my ford. I did not buy the tank guard as I don't do a lot of rough off-roading. After install, I took it to a ford dealership service center and explained what I did and had them reprogram the fuel level sensor to reflect the larger capacity. It was great to see 800 miles + to empty on the display screen. Even better was to not have to stop to refuel as often.
