Delamination

Two years ago I had no idea what it meant in the RV world. While searching for my first RV I started seeing "bubbles" and quickly learned what the bubbles indicated. During our search we found several units that were really nice MH's except they were value-less due to severe De-Lam, basically totals.

I am to a point where I am considering a newer gas class A and have a couple of questions.

Is anyone aware of a manufacturer that has sidewalls resistant to De-Lam? I guess to be resistant it probably means no Luan in the walls. I fully understand the best cure is keep the water out.

Why do the manufactures use Luan, just because it is cheap? My neighbor just bought a beautiful Fleetwood American Dream, walking across the street to look at it I could see the 5 foot wide "bubble-o- doom" on the side. His was advanced enough I would not have been caught on buying it, but it would be easy to buy one in earlier stages.

I have also wondered why the mfgr's cheap-out on luan or any non-exterior rated materials in their rigs. Seems even some higher-end rigs. I've also marveled at the bargain-basement prices on the delaminating RVs! I'm a dedicated do-it-yourselfer (meaning I'm too dumb to say "no" to a new project) with LOTS of tools and energy, so I would be tempted to investigate the possibility of purchasing and repairing a border-line basket case RV for flipping. Low cost delam repair kits are available, but I don't know the success rate, durability of the repairs and other important details. I will investigate though.

Newmar uses hung wall construction and a close copy is the Entegra. After that you get into Foretravel and Prevost range.

I have seen the term "Hung Wall" on this forum before, what is it, how is it different?

If you decide to take a 'delam' project on, there will be no criticism from this camp! I can assure you though, once you have that experience under your belt, you will not very likely take a second one on.....

Brockx,
I don't think the MH mfg's were thinking 20 years down the road when they were justifying cost of materials?

Fleetwood coaches do not enjoy a real good reputation when it comes to delam.

You might look into the Monaco and Holiday Ramblers as less like to delaminate?

"hung wall" means the wall studs are attached to the MH floor and the outside wall material is attached (hung) by gluing it to the aluminum studs. In the case of Newmar the wall and roof structure is welded aluminum with batting or foam board between each stud. Each opening be it window, door, or hatch is framed by aluminum.
Newmar have some video's of it on their site. http://www.newmarcorp.com/why-newmar...y-construction

The Strongest Sidewalls and Roofs

Newmar RV sidewalls are designed like those of residential homes, to make them more rigid and dependable. By building aluminum frames with studs 16 inches on center, your sidewalls and roof will form a strong, lightweight, integrated structure so your recreational vehicle provides you with superior insulation.
