for Andy Petree Racing to drive the No. 55 Square D-sponsored Chevy. He won his final Cup career race at Talladega and finished 18th in points. He posted three Top 10s in 2002 but suffered a broken shoulder late in the season, causing him to miss several races. Although his Cup Series run in 2000 was not successful, he made history regardless as he joined Ken Schrader, Terry Labonte, and Mark Martin as one of the drivers to, at that point, win a race in each of NASCAR's Top 3 series when he won a Craftsman Truck Series race at Martinsville. Craftsman Truck Series Due to the injury, as well as an unstable financial situation at Petree Racing, Hamilton left the Winston Cup Series for the Truck Series driving for his own team, taking the Square D sponsorship with him. Driving the No. 4 Dana Dodge Ram Hamilton picked up two wins in his first year on the circuit and finished sixth in points. The following season, he picked up four wins and clinched the championship, marking the first time since Alan Kulwicki's championship in 1992 that an owner-driver won a NASCAR championship. He switched to the No. 04 in 2005. In 2005, he started his Truck series season with a bizarre finish. He led the final laps of the 2005 Dodge Dealers 250 at Daytona International Speedway when Jimmy Spencer got by with a few laps left and the white flag flew just before a crash occurred in turn 1. During the accident, Hamilton passed Spencer for the lead. Due to the scoring-loop rules, before the accident it was initially believed that Spencer won. Spencer drove to victory circle, but not long afterward it was determined that Hamilton won; Hamilton was at the final scoring loop as he was in the lead. Hamilton later won at Mansfield and went on his way to another sixth-place points finish. He drove the No. 18 Fastenal Dodge for three races in 2006, but was diagnosed with cancer and never raced again, with his son finishing out the season. Illness and death On March 17, 2006, Hamilton announced that he had been diagnosed with head and neck cancer. He took part in the Craftsman Truck Series race that night, before starting therapy the following Monday. Kyle Busch paid tribute to Hamilton two months later for the Truck race at Lowe's Motor Speedway by
