Mount on most workvan side rails (I had it on a caravan and ive seen them on lots of work vans around town) also can bolt into roof, can be locked on both side with a padlock, and as you can see in the picture you can mount ladders real quick and lock them in place. must pickup before noon (I work late) I can help mount it or bring straps if you want to just put it on the roof and go. located on the Victoria side of Sooke. Should email i miss a lot of calls while at work
