Modification Adding doors / French Doors to garage

if your thinking of installing a french door unit made for residential house use they are really not built to be bounced and vibrated down the road. the door frames are usually wood finger jointed then glued together and will not stand up to the road. although there are some plastic,vinyl and metal frames available by special order. if you are going to chance it i would look at fiberglass doors as they may hold up better.
