You are correct that the article section has a wealth of info. The problem is my old memory is short and I would like to be able to refer to a diagram to refresh my memory.

What I had in mind was like the 'overview' of a system, as one might see with airplanes or perhaps other more complicated equipment.

I did try contacting Prevost through their web site but they need numbers I don't have so, on to plan B, calling them on Monday.

Too anal for my own good, perhaps.

Thanks, Larry
