I want to build my new workshop 32' wide X 48' long. My local truss fabrication shop has 24 2x4 trusses that are 32' 3 inches long that someone ordered but didn't pay for. I can't see how the extra 1.5 inches on each side would matter. They said they would be strong enough to hold drywall at 24" on center. There is also 2 gable trusses. they want $1500 for the set. They said normally they would be $2600
