Hmmm....a lot of RVs, boats, etc that have auxiliary batteries to run 
appliances, lighting, etc to avoid discharging the battery used for the 
engine use a relay or diode "isolator" to put the aux battery in 
parallel with the vehicle battery for charging.     I have one that uses 
a simple relay, no resistance in series, and just replaced the deep 
cycle aux battery after getting 10 years of use from it.
