No clearance problems in the garage I built,its on of those quonset hut type steelmaster metal buildings.I didnt like the looks of the sliding "airport hangar"doors it would have came with so I ordered it witout endwalls and put a regular overhead door and wooden endwalls on it,so it would blend in with the residential setting here.The building inspector was hesitant about letting me put a ten foot door on it,he was afraid I would be parking a semi in there,against zoning laws.I convinced him by showing him the blueprints for the stock doors show a ten by twelve foot high door,I only wanted 10 feet high,and told him if I couldnt park my pickup with the slide in camper on it in there,I might as well not have a garage at all.My advice,is get the highest door you can get away with--even at ten feet sometimes I wish it was more,the camper barely squeaks in and I have to block the door open with a block of wood,and thats on stock tires!. /forums/images/graemlins/doah.gif
