Extension Ladder

I carry a Telesteps at all times. I have a 22ft Little Giant that mostly stays in my garage due to it’s weight and size (though I like it immensely). I have a 32ft Werner Type 1A that I carry only when I know I’m going to need it.

My inspection vehicle is a Yukon XL, so I wind up strapping the ladder to the luggage rack. Looking for a better way to transport it without poking holes in the roof. Any ideas?
