Here is a picture of the truss layout...
Areas above the garage doors and 9" to each side with truss's highlighted in red will be cathedral ceiling.
Areas highlighted in green are flat bottom trusses with a ceiling height of 10'.
The change allows for about 3' 6" or so of added height at the areas of the garage doors where the lift is to be installed.
Garage doors are out for pricing now with the wall mounted opener...R-17 insulated doors with Stockford 3 windows in the 3rd row from the bottom...the track profile to follow the cathedral ceiling roof line similar to the 2nd pic.
