Looks reasonable to me, assuming the unit works the way they say it does.
Inrush current (caused by connecting a discharged trailer battery directly
to a charged starting battery) should be limited by the resistance of the
wire run. T'aint cheap tho, an ordinary 80 amp battery isolator shouldn't
be more than about $40, while these things start at $140 ...
