RV Construction References

Mds1 you asked a very good question, in 10 years on this forum and other searches construction,design,and materials used on each MH is not easy to find. If you go to each MFG web site, Winnebago for example and look at the structure they say "Super Structure" and describe steel framing over Al or wood which is nice but don't tell you what the wall construction is made of. Is it woven FG or random fiber? Is it polyester or epoxy resin? What is the adhesive used to bond it together. They say the align structural parts with a "Laser" which is better than a transit or tape measure. Do they use hard tooling or assy fixtures like the automotive industry? I can't find any info that tells me that. Most construction videos say we use "superior materials" and describe the process in marketing terms rather than engineering terms, what are they? Some basic assumptions that I have come to is woven FG is stronger than random fibers that I have seen in the Filon side walls. Epoxy is stronger that polyester. Thermoplastic adhesives are better in peel and shear which is how most adhesives fail. Side wall panels bonded in an autoclave produce a better bond than an vacuum or roller bond process that most mfg's use. I am sure someone that has worked in the RV industry for 20-30 years may know some of these processes and may have some incite into the construction methods. I think the only way to find out is to talk to the engineering or Mfg people at these companies once you have narrowed down the floor plan and basic drive train that would fit your needs. If you find any web sites let us know.
