Slide Out Adjustments

Hello fellow RVers. I have a 2005 alpine 36 MD. I need to adjust the main slide out. How can I get my hands on information to adjust the slide out?

Not sure there is much of anything in writing--I have made several posts on the forum for this issue regarding main slide "adjustments" on my 2003. What do you have in mind for an adjustment?

If I can find drawings on the construction of the slide out. I can make any adjustments needed. The lower portion of the main slide comes out too far.

Interesting--there is perimeter flange around the sides and top of the slide that keeps it from going out "too far." The hydraulic ram arms are connected to the floor of the slide. The top of the slide simply follows the bottom, unless obstructed. Again, not sure there are drawings--pretty much what you can see is how it works.

What are you calling too far? And what are you basing that on?

The lower portion of the slide out when extended extends about 3 inches more than the top. The slide also drags on the floor for about the first 5 inches when extending.

Both my Georgetown slides are like that. For my coach that is normal. The way to check if it is normal is to ascertain that the seals on the sides, the top and the bottom are all flush with the inside wall of the motorhome wall when the slides are extended.

As for the dragging. Can't help you much there. Mine drag too. I tried to adjust but couldn't seem to make any headway. I made a "SKI" about 6" wide and just long enough to go from the edge of slide out to the opposite wall. I used 3/16" plywood. I place it where the slide makes the most contact with the floor. When the slide starts it rides up onto the plywood and slides on the plywood using it as a buffer between the slide bottom and the floor. See the included pictures. When the slide is out I pick up my "SKI" and store it out of sight.

Do an internet search for RV Slideout Skis. You will find several variations for sale.

On my ‘01, the bottom of the slide is out more than the top, when viewed from outside, but not 3 inches. It’s flush against the wall on the inside though. See pic. The distance between the red lines is more than the yellow ones. I’ll put a tape measure on it just out of curiosity to see the difference.

I don’t know all the ins and outs of how the slide operates or adjusts. There is a small amount of ram adjustment in the yellow circle. The red circle is an adjustable stop, that sets how far the slide goes in. The blue circles are nylon/plastic slide bushings. Make sure those are there and intact.

Is your slide flush with the coach wall inside? Has the flooring been changed to something thicker than factory causing the slide to drag?

Thank you for your reply. The main slide will drag on the floor for about the first 6 inches of movement. Makes very serious noise, when movement is activated.

Thank you for your reply. Thank you for the great idea. I also forgot to mention when looking at the slide from the inside. Looking towards the drivers side. The left side of the main slide is 1 inch lower than the right side. What ever the reason. It makes a loud grinding sound when activated.

Does the slide drag on the floor at both the forward and back ends? There are white plastic support pads on the interior floor under the slide. The support pads are mounted in aluminum channels that are screwed to the floor. Try to get a look under there and make sure none of the pads are broken/missing. If the slide box is not supported evenly it could tip a bit moving in and out.


The slide moves on a pair of rectangular steel tubes that have the hydraulic rams inside them. Each one of the pair has an inner and outer tube. The last picture posted above with the blue circle shows the tubes and mentions the four plastic pads that support the inner tube. There are also four more pads on the inboard end of both of those rectangular steel tubes. You need to see that all of those are not damaged/missing or you will have too much movement of the inner tube inside the outer tube and then tipping of the slide box when it moves in and out. To inspect the inboard pads I think you are going to have to take some stuff apart.

When Western RV welded the outer tubes to the frame, if they didn't pull the inner tubes out, they would burn the Teflon pads on the inner tube. I had Western RV remove the slide and replace all the pads. That fixed my adjustment problem.

Main slide

On our 2001 newmar the slide when Al the way
In does not sit flush with the side of the motorhome. One side is a bit lower causing it to not sit flush in the frame. How would one adjust that?
