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.
