This 2015 Peterbilt 389 Fitzgerald Glider has a 600-horsepower Detroit with a 13-speed and 3.55 rears. The truck features all Talladega Fiberglass fenders, panels and visor, and all the work, along with the paint job was done by Cullins and his son. He also plans to stretch the truck from its 275-inch wheelbase to a 300-inch wheelbase. Leased to Diamond S Trucking out of Catoosa, La., Cullins hauls mostly calcium chloride. The truck has earned the nickname “Marie Laveau,” the voodoo queen of New Orleans, because Cullins says it has a curse on it – he has been hit three times.
