Unfortunately we do not have anything to say what is on your 2020 forest river salem cruise lite model 24rlxl. Spoke with Lippert and they stated this crank handle is standard for most Lippert landing gear systems as well as manual slide out systems. It has a T-Connection style end. As long at the shaft coming out for the slide has a pin in the shaft this 045-119226 will work. If it has a nut you will need the Lippert 285324 electric stabilizer jack manual crank handle.
