Of course it’ll depend on the size of your kit and if you have our standard or high clearance tubes, but on average, it takes about 20-30 minutes to set up (and break down) AirSkirts.
It’ll take a bit longer the first time, since you’ll have to do some initial preparation by applying the sharp corner and edge protectors and getting the tube positioning just right. But once you’ve got a little bit of practice, you’ll find that getting your skirts set up will be easier than backing into that campsite!
