Your picture looks like you have a short bed truck. What after-market fuel tank did you go with? I always thought the fuel tank design....OEM, left a lot to be desired, aka, 25 gallons. I did not want a long-bed, to get the larger fuel tank that GM offered. The big downside with the after-market offering, was the tank hanging below the frame rails, making them vulnerable to damage off road. This was not a problem with Hot-Shot truckers, or those who stayed on pavement.
Nice rig, did you do a BUILD on the Siverado thread? I also see that you did a mirror upgrade. My 2003 came with the telescoping trailer mirrors, which us owners have had a love/hate relationship with. A very problematic design. I have had 1 complete rebuild, and 1 motor rebuild on them. And yet I am the driver, who never adjusts them, yet, they have broken too many times, while not being abused. What brand did you go with, as Amazon offers many versions with a wide variety of satisfaction ratings.
