Question
Dave back again. The house that I leave in was built by a construction company and is about 27 years old and they used 2x4's for the whole trusses rafters, joist and for the w shape also. It is 4'8" from the bottom of the joist to the top of the rafter. Is it possible for you to send me a picture of the truss with the measurements for a 20' x 20' room with 18" extending out from the wall and a 5' height from bottom joist to top of rafter, so I could built it myself. How long should the rafters be and are the joist 10' each connected to make 20'. I would really appreciated it and if you think it's better with 2x6 for rafters I'll go with that.

Answer
Hi again,
I'm not too clever with making/sending graphics, but I will try after sending this.
The 2"x4" truss is ok. I suggested the other because thats what the building inspectors like to see in a homemade truss.
