Well not really trouble, but was running the xt in a abandoned industrial building. Someone called the cops, they showed up (did not even hear them pull up). They told me that my toy was to loud. Being good friends with a cop in town helps though, he showed up on seen a few minutes later got out of his car and said: This really is not a legal place to run this you know. He looks at the truck and says: but what would be more of a crime is to dump the rest of the gas out. So needless to say the 2 cops ran the tank dry for me. All I could do is laugh.....
