I am in the final stretch of getting my garage door install completed. We ended up replacing two 8' wooden garage doors with one 16' insulated steel door on my old house. With the new door and limited headroom my garage has, I am installing a jackshaft(side mount) garage door opener versus the conventional overhead models.

Has anyone ever had one of these installed or used one? I am going with the Liftmaster 3800....

Feedback, tips, horror stories welcome....
