NEW Beer Mug, Real Trucks Don't Have Spark Plugs

This mug is new, never used. It was given to me as a gift and I've never had a use for it. It doesn't say how much it holds, but it's big and heavy. It measures 7" tall and 3 1/2" across the top. It would make a nice gift for a diesel truck driver as it says "real trucks don't have spark plugs".
