The stage is set for "a big honkin' anniversary" celebration! Online registration for the 40th Annual Shell Rotella® SuperRigs®, which rolls into Branson, Missouri June 9-11, is officially open. Pre-registration is required. Pre-registration provides drivers with a designated parking spot and on option to select their preferred time for when they would like their truck judged. Final judging times will be determined by Shell Rotella representatives.
