Shirley just called and asked me to do some channeling for her:
Channeling is lowering the body on the frame. In the pictures this truck doesn't look channeled to me. The floor appears to be in the stock location, which would almost have to change if it where channeled.
Closing up the frame is called 'boxing' the frame.
