Can I Add Another Slide Out to My Motorhome?

by Rudy Bailey
(Somerset KY)

I have a 2003 Fleetwood Providence 39D RV with 2 slides. We are wanting to know if a slide could be added to this RV. It is on a Freightliner Chassis.

Thank you.

ANSWER: Hi Rudy thanks for submitting your question on our Ask an RV Question Page.

The good news is that in all likelihood you can add another slide to your motorhome.

Now for the bad news; first and foremost you need to find a company that is willing and capable of adding a slide-out to a motorhome. Your best bet is to contact one of the larger RV Dealerships in your area and see if there is a company in your area that can properly do the job.

Once you find a company that is willing to do it; the first question you should ask them is how many slides have they installed in the past. This is not a simple job; depending on where the slide-out is located it could require moving electric wiring, water lines and even propane lines. If these modifications are not properly done you could experience damage to the motorhome or bodily injury.

Another factor to keep in mind is that the structure of the motorhome is going to be affected and will need to be properly reinforced to take the weight of the new slide as well as to compensate for the hole cut
into the side of your motorhome.

You also need to find out how long the company that installs the new slide-out system on your motorhome guarantees their work for leaking, failure, etc.

Another factor to keep in mind is that adding a slide to your Motorhome is going to also add additional weight to your RV which will affect your Net Carrying Capacity (NCC). This is the actual amount of cargo safely allowed in your motorhome. This is sometimes also listed as CCC (Cargo Carrying Capacity)

Now for the big But; you may find that the cost of adding another slide-out to your Motorhome may be prohibitive. Depending on the size and location of the slide-out you may find the cost starting at around $15,000.00. The larger the slide-out and the more modifications that have to be done to the motorhome to accommodate the slide-out; the more expensive it will be.

Lastly, unlike when you add a room to your house; you will not recoup the cost of adding the slide-out to your motorhome when you sell it or trade it in.
