Jaime,
What you are saying doesn`t really make sense to me. If the flared part of the side-rails are to the rear, this effectively means that the tramp section up front and lateral is fully gripped by the side-rails. In the opposite scenario (flared portion up front), the tramp is clearly un-secured for several inches because of the flared opening.
What I don`t understand is how can the latter configuration (flared up front) possibly do a better job holding the tramp over the long-term as you suggest. Can you clarify this?
Thanks,
Dave
