The first step is to measure the amount of sagging on your RV slide out. Measure the distance from the sidewall of the coach to the outside edge of the slideout wall (both at the top and bottom) to determine how much sag you’re dealing with. If the measurements are not equal (or extremely close), you have some sag to tackle.

5.Replace any damaged or worn-out components, such as brackets, rollers, or guide rails.

6.Use jacks to lift the slide-out room to its proper position, then place a block of wood or other support under it to keep it in place.

14. Replace any damaged or worn-out belts, gears, or other components in the slide-out motor or hydraulic system.



It is also important to use slide out supports to help reduce the potential for sagging. These supports are affordable and easy to use, functioning very similar to a jack which will help take the weight off of the top support bar in your slideout.

20.Consider upgrading to a more advanced slide-out system that has a higher weight capacity and better support features if necessary.



Finally, it is important to avoid putting too much weight on the slide, especially when it's extended. Distribute any weight throughout the rig's interior. This will help prevent further sagging and keep your RV slide out in good condition.
