I have a 90 gallon RDS aux diesel fuel tank in the 8 foot bed of my 2019 3500 dually. For those that don’t know, that particular tank is taller than the bed rails by about 1.5 inches and, to make matters worse, the filler neck top sits about 3” above the bed rails!
Not to worry, I ordered the Truxedo brand soft roll up tonneau because it actually will sit above the rails by about 1.5” which allows it to clear the top of the tank and all of the plugs and the roll-over vent valve.
Which only leaves the filler port. So, on my brand new tonneau cover…I cut a hole in it so that the filler port sticks out of the cover!
Take a look at the photos and see what you think.
As you can see, I found a rubber cap I had laying around that perfectly fits over the locking gas cap!
