[QUOTE=elundquist;1015755]Using solid wood leads to many problems!
In a normal home you have solid wood framing to nail solid wood trim to the walls. In mobile homes and RVs you have composite walls that will not hold nails or screws, so solid wood trim would just warp under the moisture changes and pull free.
The engineered products are more stable to moisture changes unless they are soaked with water.
The best option for quality wood work in a RV would be real wood veneer on a non-wood fiber base/structure.
I was thinking about building a custom RV and found a great product for interior wood work. It was a composite product made from carbon fiber and looked like cardboard. I found some info on applying wood veneer to it, but in the end it was really expensive!
The only response I have for this is that when I built our custom W 900 Kenworth MH in 1976 I took the compleated chassis cab over to a shop in Napenee In. that would build custom coaches,horse trailer LQ's , and the like.The cabinet work was all either solid , real wood ,or cabinet grade plywood. Our 2009 Merhow LQ horse trailer is also solid,real oak,except for cabinet grade oak veneer plywood for drawer bottoms.Both of these units are just as nice today as when they were built. The only cardboard used*was what they put dow on the floor when they were building it.
