Rear stear axle advise ?!

Yes it was great fun to drive forwards, as for the reversing just very small movements, to complete the blindside 90 degree turn I only needed about half a turn or just over to get it around the corner! I believe the axles people are talking about locking off are the ones that are normal on tri axle trailers and just move with the momentum of the trailer ect. They have no mechanism moving them so if you try to reverse with these ones without locking them off you will fail miserably and the trailer will just be crabbing because of the rear axle.
