My 2010 Designer 35RLTS has a Progressive Dynamics Model PD9280A. The original one died a couple of years ago after 8 years full time service. The replacement with the same model number is a couple of inches shorter so one new mounting hole was needed, but otherwise was a direct replacement. Problem solved.
