Azdel or equivalent

FRP Fiber reinforced panel would be my first thought. The panels are available in 4'x8' panels and are totally waterproof. I had them in my car wash for 8 years with no problems.
I cant remember what the price was, but they are not cheap, at least the version (white pebble finish) that I had. They are commonly used in commercial kitchens, medical facilities and farms.
Maybe this would give you some ideas. Panels

They have basically no structural strength, at least in the vervion I used, but there should be others which may work for you.
There are also some pvc based products.

This could give you a starting place on buying Azdel.. Also google, or Bing, azdel for sale. It just happens to be made a couple towns over in Shelby NC.

I have googled Azdel every which way I can think of. Most place just praise the product. Some are wholesale distributor (not looking for a semi load).

This one is selling left over/over stock panels, but at an excellent price !

These are used for sheathing, so I need shear strength to prevent the walls from racking front to back.

I'm not sure what your application is but in general most any resin that is fiber reinforced will be good enough for a side wall of a MH. Azdel is just a thermoplastic material(polypropylene) and most Azdel products are FRP . Epoxy reinforced with a woven fiberglass will be stronger. Woven FG will be better in shear and stronger in general(tension,compression,bending etc) than random fibers like Filon. Azdel, Lamilux, FRP epoxy or polyester will all work for sidewall. It will be next to impossible to get mechanical properties like shear strength from their web sites so you will have to call and talk to their technical dept if shear strength is important to your application..
