Love It!
Everything went as planed. Took me about an hour to install. Very straight forward. The only thing is the price is a little high but would buy it again if needed.

RDS® 011025 - 1.5" Diesel Auxiliary Installation Kit
Removed right rear fender well to get the fill lines out. If you do that first it's a lot easier. Took about 2 hours to install. That doesn't include your particular installation of the tank lines valves etc. The particular tank that I used was a tight fit, so it took about 2 hours trying different configurations with the shut off valve. So in the end the shut off valve is mounted inside the fender well instead of right on the tank. Directions would be nice to clarify some questions about the check valve position. Installed in accordance with the system diagram and it works fine. Very straight forward.
