Dan,
That is what I have seen. Any extra voltage drop from another inline
item will make that even less. I do not think that over charging will
be a problem from a tow vehical. Also consider that the tow vehical is
not charging very long. Only when you travel which would be at most 10
hours a day and possible onlly 4. On my Ford, the charge line is
disconnected by the vehical. I would think others do the same.
