Renfrow would once again finish 30th in points during 1999. He started off his season by replacing the injured Rick Carelli in his #6 RE/MAX Chevy. However, in three starts, Renfrow only managed a best finish of 15th at I-70, before Carelli came back. Renfrow then moved back to the #41 Dodge, now owned by TKO Motorsports. He ran solidly in his six starts for that team. In his first start for the team, he started on the outside pole at Michigan, before finishing 26th. After that, he had five straight top-20 finishes to close out the year. This included a 9th at Richmond, matching his career best.
