US Tower shows the wrong anchor bolt size for the HDX5106.  I wasted
$500 buying the wrong bolts; fortunately I discovered this before
pouring the cement.  (I imagine UST would say that I should have
purchased the bolts from them.  There is also the previously discussed
issue of J-bolts vs the bolts-with-washers as supplied by UST).  Also, 
the calcs have numerous obvious errors in them.  I got schematics of
the winch box from other hams after UST refused to supply them.  YMMV.
