Like all things in life there are good and bad things about wood for a structure.
A lot of people think that aluminum is the perfect building material and has no faults. It's not. Aluminum work hardens and cracks. Welds break. Fiberglass can delam.
There is problems with wood to. It can rot.
About the best material I found for building trailers is steel. It doesn't work harden and it doesn't rot. But then again there is the rust factor.
I guess it's true. There is not perfect building material.
