My coach is 13'to the top of my KingDome, so if your coach is the same, the door opening alone should be at least 14' high and the building at least sixteen feet. Give yourself a little room to the top and the sides.

New Tiffins list the height at 13 feet to the top of the satellite dome. My antennas clear at 13 feet 1 inch. go for 14 feet as suggested. My width is 12 feet which works fine. Leave room for future new MH purchases as they seem to get taller.

I have a "carport" it has a 14 foot clearance overhead..there is one thing I wish I had done...I back the rv in, and the doors on the compartments won't open all the way...wish I had built it 16 wide instead of 14 ft...this is one place where size does count...good luck

Remember, an overhead door that is 14' high (most states have a 13'6" max vehicle height limit) will require higher interior height under the rafters for the door. Sidewall height for standard overhead door might need to be 16'. A front slider door or doors will get buy at 14' with 14' sidewalls on an end opening. A side opening door will require room for a header (10-12") above the door opening.

If you specify an odd sidewall height like 14'3" or 15', each standard length piece of siding (16')will need to be cut, resulting in waste in material and dollars for labor.

In any event a 14' high minimum door opening should take you all the way.

My 30'x 50' pole barn has 12' high walls and 11'9" high doors (after pouring concrete floor). I needed to get 2 low profile AC units installed on my 2007 Class A to get it in.

I started with nothing... and have most of it left.

I put in a 14 by 18 foot door. It makes backing in a breeze. I can fit any motorhome of legal height in there too as the inside is 16 foot high.
ALso make sure you put a man door so you can get in and out without lifting the big door all the time.

Hey Toyman,
I had not planned to buy anything much taller than your Sprinter when I designed my building, but I'm glad I made the center door 12 feet high because I now have my eye on a Winnebago Via (Class A minus) which is just under 11 feet tall. Drive on down the penensula past the marina and you will see several tall motorhome garages. Send me a PM if you want to check out one made for an Allegro Bus.

I would go with 14x14. My coach is 12'8" at the tallest point and only 96" wide, so I'd have a lot of room, but I'll probably have a larger one sometime.

The OP has a classic GMC coach, so it really only needs a 12' door (look at his sig line), but again if he plans on buying a larger coach sometime, make the structure that will accomodate it.

My garage opening ie 12 wide and 14 high. Glad I didn't build it any smaller, the additional width allows the mirrors to not have to be moved.
