Ask Dave: Is it OK to store an RV with the slide room out?

Answers to questions about RV Repair and Maintenance from RV expert Dave Solberg, author of the RV Handbook and the managing editor of the RV Repair Club. This column appears Monday through Saturday in the RV Travel and RV Daily Tips newsletters. (Sign up for an email reminder for each new issue if you do not already receive one.) Today Dave discusses if it’s OK to store an RV with the slide room out.

Dear Dave,
I keep my 38’ 5th wheel stored in a fully enclosed building year-round with the slides out when not camping. Can leaving the slides out for long periods of time cause any damage to the frame or other structural components of camper? —Spencer

Dear Spencer,
Slide room mechanisms are designed to hold the weight of the room on rails, tracks, rollers, and even a slight amount resting against the sidewall for extended amounts of time. I have never actually seen or heard of a recommendation provided by any of the mechanism manufacturers or even RV manufacturers. However, it is generally a common practice to store the rig with the slide rooms retracted.

You do see models sitting on dealers’ lots for weeks and even months with the room extended. That’s typically done for show and more room inside.

I don’t believe the chassis or rails could be damaged. However, here are several things I have noticed when a slide room is left out for an extended period of time.

Moisture leaks

Leaving the slide room extended in some models leaves a small hole or gap at the bottom of the slide room at the sidewall. Rain and snow can blow inside and cause moisture damage.  Even though the flange of the slide room trim presses against a bulb seal, a good wind can bounce the slide room during a rainstorm and moisture can get inside.

Seal exposure

Most slide rooms have a flap seal and bulb seal on the flange. Leaving the room extended during storage exposes it to weather, especially the sun. That can deteriorate the seal and cause moisture issues.

Additional weight on roof

Leaving a slide room extended in cold weather conditions means snow piling up on the roof of the slide room. That causes additional weight on it which is not designed into the mechanism. The amount of damage this could cause depends on the engineering of the mechanism as well as the structural integrity of the foundation and the sidewall framework.  It’s something that would be hard to track or document; however, I don’t think it’s worth the risk.

Awning cover exposure

Your slide room may have an awning that extends out with the room to help keep water out as well as keep debris such as sticks and acorns off the top of your rig, Extended exposure can ruin an awning quickly.

More storage space required

Most storage facilities charge by the square foot. A typical rig is 102.5” wide. Extending the slide rooms can add 2′-3’ on each side, which could cost a lot more money just to have the rooms out!

Bottom line

In my opinion, it’s best to store the unit by first conditioning the slide room seals with an approved conditioner such as Protect All, then retract the rooms and button them up for a long winter’s nap!

I store my fifthwheel in an enclosed building with the slide extended but not to the point of compressing the seal. The carpet that would be under the retracted slide doesn’t get deformed as badly this way. I have been storing it this way for 9 years without any problem.

Well THAT was a non-answer…The question regarded storing in a ‘fully enclosed building’.

You caught that too! Guess he wasn’t so much answering the original asker but the rest of us (maybe?).

If you are not using the space gained by having the slide out while in storage, then I suggest you consider the long term stress incurred by the frame and mechanism by keeping the slides out. In the “in” position, the weight is better balanced in the sidewall of the RV.

Dave answered the OP’s question in his very first paragraph. However, he did expound upon storing a RV in outside conditions and what to look for when doing so. I store my coach with slides out under my house in a huge RV Port. The only time the slides are in is when we are traveling from point A to point B.

How is what Spenser is asking and John is doing any different than what us full-timers who stay in a location for 4 to 6 months at a time do? Not sure the answer has much merit.

I agree, and on the question of snow weight .. what about the weight of 4 people, a big dog and everything else that resides in a living room/dining room slide for a full timer?
I do appreciate Dave’s column but hope he will read and answer the questions more deliberately.

The question actually asked about keeping the slides extended inside a fully enclosed building, but the answer addressed the question from the perspective of the unit being stored outside. I also store my ClassA inside our fully enclosed climate controlled RVBarn with the slides extended most of the time, because it makes it much easier to load and unload and work on the unit between trips.
