In this article I’m going to be talking about RV slide out repairs. And the top five tips for maintaining and protecting your RV slide outs.
So that way you can avoid a lot of the slide repairs that can be very costly to fix.
Of course, one thing’s for sure. And that is that RV slides provide a lot more living space inside an RV.

In fact, RV manufacturers can extend up to 50% of an RV’s living space by using enough slides.

RV Slide Outs Can Have Problems
But slide out rooms can have their problems too. And that’s especially true if they’re not maintained or operated correctly.
And that eventually often leads to RV slide out repairs becoming necessary.
In fact, there are many RVers these days that absolutely avoid slide rooms altogether.
Because of the potential problems that they have heard about or seen themselves.
But by following the tips in this article, you can avoid a lot of those issues and problems. Ones that can become very expensive to repair.
Not All Slide Outs Are The Same
First of all though, let me say this. Not all RV slide rooms operate the same way.
Yes, they all go out and then come back into the RV. But the mechanism that causes them to do that can be very different from one RV to another.
And there are four main kinds of slide out systems in use today in most RVs you’ll see.
RV Slide System #1
The first one we’ll talk about is the electric rack and pinion type of system.
Now rack and pinion just means that you have a circular gear that moves on top of a lateral gear. And moves the slide room in and out.

It’s the most common type of mechanism used because it’s very reliable. Also because there’s very few moving parts too.
So RV manufacturers love using that system and installing it at the factory.
Unfortunately, it can also be one of the more expensive systems to install correctly.
RV Slide Out System #2
The second slide system we’re going to talk about has a little bit of a bad reputation though.
It’s the Schwintek slide room system. And Schwintek uses worm gears at each end of the slide to move the slide in and out.

It’s actually a fairly reliable system overall. But some RV manufacturers these days have been using them in ways it was not designed to be used.
For instance, they may use it on very long and heavy slides often referred to as “super slides”.
But Schwintek is not designed for that. It’s best used for smaller slides like you find in an RV bedroom.
And as long as it is used in the way it was designed, it usually works just fine.
RV Slide Mechanism #3
Now the third type of system we’ll talk about is hydraulic. It uses a motor and a pump and somewhere there is a reservoir for the hydraulic fluid.

Now if you know anything about hydraulics you know that you can use it to move really heavy things around.
So a hydraulic slide mechanism works very well for those bigger and longer super slides I mentioned earlier.
And the other thing that you’ll notice is that as you operate a hydraulic slide it moves in and out usually a lot faster too.
Especially when compared to the electric rack and pinion type of slide system. In fact, it can move so fast that it’s almost scary to some people.
RV Slide Out System #4
Now the last system we’ll talk about today is a cable slide room system. It’s a little more expensive and therefore it’s not used quite as often.
But it uses cables that bring the slide out and then cables that pull it back in.

Usually you only see a couple of cables outside but there are more that are inside the mechanism.
And once again, this kind of system is best used on smaller slides.
Although it is more robust than the Schwintek system mentioned above.
OK, those are the four most commonly used types of slide systems in RVs these days.
But remember that maintenance is going to be required on all of these systems to some degree.
So here are my five top tips for maintaining RV slide rooms to get the best service from them.
RV Slide Out Repairs – Maintenance Tip #1
And the number one tip is make sure that you lubricate any moving metal parts that are touching one another.
You’ll want to do that to keep them moving smoothly and cut down on friction.
However, it’s important to use the right lubrication too. So don’t use anything other than a dry lubrication like you see here.
Because if you use something else, very often dirt or debris will be attracted to that lubricant.
And that can even gum up the system instead and make it worse.
So lubricate moving metal parts and use a dry lube for that task.
Slide Out Tip #2
Now the second tip is to also lubricate your slide seals very often as well.
And slide seals are the rubber seals that go all the way around your slide room.
The purpose of them is to keep any kind of weather and debris out of your RV.
But especially to prevent water from penetrating in and around the slide room.
And replacing a slide seal when it’s damaged can cost you thousands of dollars. So you really want to pay attention to your slide room seals.
And the number one thing that breaks down rubber slide seals is ultraviolet rays from the sun.
So while your slide is extended it’s a good idea to lubricate and protect the seals.
And the best kind of lubrication you can use in my opinion is a high quality ultraviolet inhibitor. Like 303 Aerospace Protectant.

I have used this product for years now. And it keeps my slide seals supple and protected from UV damage.
Prevent RV Slide Out Repairs – Tip #3
OK, the third tip for today is also about slide seals. And that is that you need to keep them flipped into place when the slide is extended.
Now this is one of the most common problems I see as an RV inspector.
And that is that that some of the slide seals don’t completely flip out when the slide is extended.

So when you have the seal not flipping out like it should, water can penetrate into your slide room easily.
And when it does, it can start rotting walls, ceilings and floors away quickly. And that’s a very expensive repair.
So you need to keep those slide seals flipped out when the slide is extended.
And keep them nice and tight against the wall of the slide to protect the slide interior.
A Couple Of Suggestions On How To Do This
Now there’s a couple ways you can do this. First of all, you can do it manually.
So you go around after you set up your RV and put your slides out. And you check and make sure that all the slide seals did flip correctly.
But if they didn’t, you could take a ladder and then run your hand up behind the seal and flip it back into place manually like you see here.

But there’s a way to do it automatically too. I know because I had a very stubborn slide seal on my kitchen slide.
It just would not flip out and back in no matter what I did. So I found a suggestion from another RVer that works really well for me.
And that is that he used these little small half inch plastic furniture bumper stops that you can find for sale almost anywhere.
But you can find them pretty cheap on Amazon at this link.
Then he placed them about halfway down the sidewall of the slide about 18 inches apart from top to bottom.

Now when you do that, you just stick them right on the slide side wall after prepping it with alcohol.
Then as the slide goes out, it flips the seal right out. And likewise as the slide goes in it flips it back in automatically.
The good news is that these furniture stops have been on my slide sidewall for years now. And they work great!
Prevent RV Slide Out Repairs With Tip #4
Now tip number four is to get to know your RV slide out rooms very well.
And what I mean by that is you should listen to them carefully as they operate in and out. Get to know the sounds they make in normal use.
Now all slide out rooms make sounds of various kinds. And very often there’s little squeaks and maybe a slight moan or two.
But what you don’t want to hear are loud sounds. Like pops or grinding noises.
In fact, usually loud sounds of any type that means something is not right.
So when you start hearing that, you need to give that attention right away.
Slide Repairs That I Made on My RV
In fact, let me tell you about another one of my slides that I had this kind of issue with. And that’s my living room slide.
Now it’s operated fine for years going in and out without any trouble. But I always listen very carefully to all my slides for anything out of the ordinary.
And this one started making some funny noises that it hadn’t made before.
So I went online and did some research on the noise I was hearing. And I learned about an issue that these electric rack and pinion systems can have.
And that’s where the slide motor housing loosens up over time. The bolts that hold it together just loosen up through use and vibration.

And therefore that causes problems with the slide that you can begin to hear. Before it gets really serious and needs repair.
So I went out there to check the motor housing bolts. And sure enough, they needed tightening.
So I tightened them all back down and now my slide moves in and out just like it should. And it doesn’t make that unusual sound anymore.
So know your slides and the sounds it makes that can be considered normal. And take action when you hear sounds that aren’t normal.
For me, I would have never prevented slide damage if I hadn’t been listening to my slide very carefully.
Then if you find anything that’s out of the ordinary, do research on it and get it fixed.
You can do it yourself or get an RV service tech in and get it fixed before it becomes a major issue.
Conclusion
Now here’s my fifth and final tip. Maintaining your RV slide outs is going to take dedication and effort on your part.
So you need to schedule regular maintenance to protect your RV slide out rooms.
But it will pay you back many times over in fewer costly repairs and less stress and frustration.
And these tips that I’ve given you will help you keep your slides in great shape and operating smoothly for many years to come.
Have safe and happy travels my friends!
