Re spelling and grammar, etc, I'm with the Prof.
Re Motor mover - I have a Powertouch Evolution with auto engage and, so far, have had no problems during the five years I've had it and on two vans. Previously I had a mover with manual engagement which was manageable with a long-arm wrench. Not sure whether I could have done it had the mover had a cross-bar where both sides were engaged together.
The auto engage Evolution does come with a manual override tool which, so far, has stayed in by toolbox.
