For what it's worth, the rack is pretty stout and secures pretty well. Also, there's a loop of aircraft cable that loops around the ladder once in place to hopefully prevent the ladder from becoming a projectile. I think the combination of everything makes it pretty safe, although I'm sure in a severe wreck, bad things could happen.
Just got the rack myself and it is definitely heavy duty and nice. But with a bulkhead, I'm not sure how well it will work. I guess another alternative would of been the Jet Rack ladder system, not as pretty but only 1/2 the cost of the Weather Guard.
