How to Figure Out What Replacement Slide Out Motor Is Needed for a 2020 Grand Design Solitude  

Updated 01/19/2026 | Published 08/12/2024

Question:

I have a 2020 Grand Design Solitude 3550BH-R. I was curious, without taking the underbelly material off to get to the motor, if this would be a compatible replacement motor for the main slides not the schwintek bedroom slide. Thanks for your help.. Alex

Alex, unfortunately there is no way to know that. The only way to find out if the Replacement Gear Motor Assembly for Slide-Out Motor Assembly # LC387523 would be the correct replacement or not, is to physically check the motor and see what it is.

Hey Alex, were you able to check the motor on your Solitude to see if it matches the replacement gear motor assembly? Knowing what you found could help others trying to confirm the right fit for their slide-out system.
