Thank you all for  all for the input.  I spent a chunk of time yesterday
online trying to learn some more about all this.  I also looked around at
quality generators, online,  and found a good source for that Honda 2000ie
at about $849 shipping included.  Appx the same cost for an equivalent
Yamaha brand.  I should just bite the bullet and get one of those.  But
since I am only an occaisional user of a generator and I already have one
that 'sort of works'...I just hate the concept of buying another and I can
see my S.O. saying..."Hey, the new generator is quiet, let's watch a movie
tonight, and turn on the heater, and and and..."  All of a sudden, I
will find myself maintaining a bunch of additional electrical widgets that
we happily do  without now....And when we go on Vanagon trips, I can see
being asked to 'bring the generator, we can run a heater and and and...."
  So my plan is to *try again* on a different battery charger with that
coleman genset...see if I can find a charger that is NOT solid state, one
that will work with my "Flintstones" generator so I can make it through this
trip by charging my coach batteries with a secondary accessory charger when
the sun is gone for 2 days and my batteries go flat without the solar panel
working.  When I get back to the Northwest I'll get more serious about
finding a good used Honda or maybe decide to just buy a new one and E-bay
away the Coleman Powermate..
