Yes, the JT's Strong Arm Jack Stabilizer Kit for Travel Trailers # LC191025 will work great in adding more stabilization to your 2022 Rockwood 2881S so that when your washer is running your trailer isn't jumping around.
This kit includes 6 stabilizer tubes so you will use 4 in the front, and 2 for the rear, will telescope to fit perfectly with any application, and securely locks in place with a simple twist of the handle.
I have attached both a review and install video for you to check... view full answer...
