I am planning to start building a shop in the next month and would like to maximize my door height. I have always gone by the 2' rule of thumb, 2' less then ceiling height for overhead door sizing. I know I can get 12" clearance track. That does not allow any room for an opener. I have read some threads on here where guys have referenced a Liftmaster 3800. I would love to hear from some of you out there about these. Are they any better then the old "iDrive" units Wayne Dalton used to sell? I ask because I had a couple of those and they were trouble. Thanks for any information.
