We have a 2010 19 foot, with AC on top; it also has the lifted axle
. It measures just under 11 feet, hooked up to our F150. Too tall to get into our carport, where the 16 fit just fine. We now store it with a cover, in the yard.
Our friends, who have a Chinook, modified their storage shed: cut out an area, and have a pulley to lift that piece of wood to allow their Chinook to fit into their storage area. just a thought, in case it would work for you. Was not an option for us.
