Why wood roof trusses?

But, my house is not bouncing down the road twisting all the time. There is a reason wooden boats are no so popular anymore and large ships are made out of metal.

Wood has lost favor mostly for economic reasons. Companies can pump out finished fiberglass and metal boats in very few labor hours. It can take a month for an equivalent wooden boat and with a good chunk of the cost is in tons of labor. For example, you can buy a plastic canoe for around $600. A wood strip version would cost well over $1,600. The larger the boat, the worse the economics.

Wood boats are still quite popular especially with the self builders. I'm in the early stages of building a new canoe out of wood. There's tons of sailboats, yachts, and fishing boats, etc trolling around out there that were built 30+ years ago. Wood has been the choice around the world for thousands of years. Materials are cheap and easy to get, it's stronger than steel, resilient, and easy to modify. Coat it with epoxy and you got a boat that can easily last 20+ years. Maintenance is pretty much a wash between materials. All boats require a lot oyf maintenance and the material just dictates the method.

I know off topic but would love to have a old restored Chris Craft wood runabout. Back to topic wood does have some advantages in RV'S along with the negatives. They have already been covered so I won't repeat them.
