Slide Outs, RV Additions, Slide Out Units 

• Electric system motors feature integral locks to positively lock the room in place every time, eliminating room drift and seal relaxation
• Rack and gear synchronization system maintains room squareness to within 1/8" from side-to-side during room travel
• Drive gears and slide-rail support rollers are concentric ensuring proper alignment and mesh between racks and gears
• Shafts/gears are oil impregnated to eliminate oxidation and to ensure smooth, quiet operation
• Mechanical adjustability provides tight room sealing

In the last 10 years, in the RV industry there is a trend towards having more and more space in your coach when parked.
 Instead of making the coaches  longer, they are adapting them  to be wider. This trend has trickled over to the bus conversion industry. Whenever considering adding slide-outs to your chassis, especially with an MCI monocoque chassis, you want to be sure you have an expert to install this for you. The average expense is approximately $1000-$1500. per foot. Depending on who's designing it, you can have as many as four units installed, almost doubling the size of your coach when parked.
Ask about our Rack and pinion System using new two heavy steel rails. We use a unique system designed 18 years ago just for the MCI chassis. If one rail moves 1/4" the other rail has to move 1/4"' .. These two rails are synchronized with a axle that can not let one side go out without the other .. It can not tweak .. designed 18 years ago just for the MCI chassis. 

Because the MCI is a  monocoque construction, you need to be very careful how you install a large room addition slide out. The mere fact that you are installing a very large opening in the side of the coach can very well destroy it. The slide out must be engineered in such a way that you add strength to your coach, not remove it. 
 

We have been installing commercial grade slide outs for the trade show and exhibition industry since the 1970s. We started with other coaches and blended over to MCI's because of the popularity of this coach. Our design has not yet been duplicated by many in the industry. 

Usually when you have a slide out, that slides in and out of the side of the coach, you need a glide system similar to that of drawer glides or a large filing cabinet glide. This glide system needs to be mounted in the  floor. In order to mount this type of system, the structural engineering for that coach has to be disrupted. 
 

Our approach is not to disrupt the floor area. We simply re-strengthen the opening in some of the floor area, but we transfer our load in our glide system in the very strong floor & ceiling. This method can also be hidden very easily. This design, in combination with a rack and pinion  system  we designed in the 1970s and have perfected since, has proven itself to be one of the best designs, if not the best. 

These are images of one of the new 2007 prototype slide outs. This is a late model MCI 102-A3 to which we are adding a 13 foot x 30 inch slide out. Watch for more images as work progresses.
