As I went to fill up the beast the other day , I couldn't get the gas cap off! I don't know why or how it happened but the gas cap just wouldn't come off, all it would do is turn and here I am almost on empty. Went to my dealer here in Sanford and talk about fast service, in and out in 20 min. New gas cap and I'm all happy with everything except filling up the truck. Question: has anyone else had an issue with the gas cap?
