My cowl is about 9 1/2 inches wide; fine if you have padded seats and don't get a prop in your armpit. From the top of the cabane struts to the ground in about 19 1/2 inches, and I am using Skylight 4" wheels inside the pants. My plane goes to the field assembled in the back of my shortbed/covered pickup. If you use the carrying/assembly unit, you will have to add to the height. Can't you put her at an angle?
