I went with this unit:
http://www.progressivedyn.com/prod_details/rv_conv/rv_converter_pd9130_2.html
and added their 'Charge Wizard' to it.  Check their bargin center, I picked
one up off that page for several dollars below their list price.  Went with
this unit at the suggestion of Dennis Haynes based on his experience with
larger motor homes.  There are probably cheaper or more compact products out
there but I don't regret buying this one.
