I picked up a bunch of free trailers from a guy I know not too far from me. I used straps that were strong enough to hold the trailer down but in a bad spot to where they would get cut on a bumpy road.
One trailer fell off my trailer, but luckily did not hit any cars and no cars hit it. When the trailer fell off my trailer, one of the leg jacks got stuck on the back of my trailer ramp. I was able to pull over after 1000 feet of driving and then I cut the leg off of the trailer and left it for about 30 minutes so I could then return with my mini Scl 1000 to put it back onto the trailer and take it back to my property.
