After you get it installed the first time it would only take 5 minutes to remove. Except if you have a windshield there is 2 bolts that hold it there, you could use snaps if so inclined.
If you just want to remove it for trailering I don't see why you couldn't just roll it up and tie it at the top of the windshield. I never remove my windshield when trailering and had it up to 70 mph they are plenty strong enough.
Yep, 5 minutes after you put it on first time. I pulled mine with top on at 65 mph but pioneer was backed on trailer and it did good. I pulled it today forward facing and it was flapping in the wind so I pulled over and removed it in less than 5 minutes. I enjoy the top and like being able to remove so quick.
