How accurate is the DTE reading??? Well, I found out. I was running the tank down as far as I could to install the tank vet mod so I went to the point that the DTE stoped giving me a reading and only read LOW FUEL. I had 40 or more Gallons in my RDS Aux tank so I wasn't going to be stranded. I don't think that there was a gal. left in the tank when my son and I pulled it.
Made the tank very light and easy to work with and didn't even use a jack to drop it!:-laf Not sure if this is the way all the new trucks are but beware that it is much less forgiving than it used to be if you ignore the warning!
