Just traveled over 1,000 miles no problem getting Diesel I carry 150 gallons and always fuel when at 1/2 tank just to be on the safe side. This trip we ended on a two lane road with road construction and was stopped cold 30 minutes waiting for a pilot car so be careful and always fuel early.
You are so correct the polications are trying to scare everyone don't listen to them and stay clear of the fake new stories
You should be fine always fuel when you are close to 1/2 tank I carry 150 gallons and always fuel at 1/2 to 3/4 tank yes some say I fuel to soon but at 150 gallons I can travel 1,000 miles which will get me home from where I am. We have not had any fuel shortage on the west coast and I try to fuel at the Indian casino's where fuel is cheaper
