http://www.rv.net/Forum/index.cfm/fuseaction/thread/tid/26852543/srt/pa/pging/1/page/1.cfmCheck out this thread. I made a fuse switch for $12.67. It works like a charm installed on my 2013 Honda crv.
Previously I had a 2004 Honda crv that I could tow all day long and multiple days with no battery starting problems, However the newer crv's have more hidden parasitic elect. draws on them that will deplete your battery.
Yes a charge line or install a fuse switch.
In my case I did not have a 12Volts at my elect. pin connector and this was a super easy solution that works just fine and easier than running another wire etc. from coach to crv.
