Hi to all.

Does anybody know what common types of 2x2 lumber is used for constructing RV walls?

I can find so many posts about wood vs aluminum etc, yet nothing about what actual types of wood is being used in modern RV framing construction.

The "type" of 2x2 wood used does not really make a difference in the strength.. That is because the walls, roof and floor are actually "truss" systems.

The paneling on the walls are glued and stapled to the wall framing, this makes a strong but yet lightweight truss..

Take the outside siding off and the inside paneling off and it would not take much effort to demolish a RV..

The RV industry uses what ever evergreen type of wood (generically called "pine") they can get at the lowest price and it depends on the availability of species closest to them.. It is light weight, fairly strong and inexpensive compared to many other woods like cherry, oak, maple..
