It was announced on April 14, 2011 that Duno would run the entire 2011 ARCA Racing Series presented by Menards season for Sheltra Motorsports. Over the first five races of the season, Duno had a best starting position of 8th (Talladega) and a best finishing position of 15th (Toledo) with two DNF's. Duno was originally awarded the pole position due to qualifying being rained out for the Menards 200 presented by Federated Car Care at Toledo Speedway. Unfortunately, she had to start that race at the back of the field in her backup car due to crashing in the final practice.
