[Elecraft] remoting KPA500 tuner at antenna base

I know this has been covered once before but I am wondering if anyone has
any further info on using the KPA500 remotely at a vertical antenna base?
The pictures from the previous discussion are no longer available.  I am
not seeing much in the archives.

So, here's my dilemma:

I have been using a MFJ tuner which has just crapped out. It figures as it
is poorly rated, but there is not much available for tuning higher power
installations (read: KPA500). So the question is: If I set up a KAT500 for
only antenna 1 and put it in automatic mode, to always power up if
connected to 12V will it automatically tune my vertical with no other
intervention from me? My installation is such that if I need to reprogram
it with newer firmware  I can just bring the tuner to the shack. I do not
need to change antennas, manually tune or flip between auto and manual or
byp.  Has anyone done this and how has it worked?  Has weather been an
issue if properly protected?

If this looks like it would work for me, does anyone have a god suggestion
for a weather proof box to mount it in?  It needs to survive the upstate NY
winters.  I am thinking Pelican or similar.

OK to reply off list too.
