This is my proposed plan to charge a couple of deep cycle batteries that will be mounted in the back of my truck.
These will normally get charged from the RV Trailer PD9260C 60AMP setup but for the times I am just running the truck hopefully I can re-charge them using the truck alternator.
The risk as I can see it is the truck alternator big enough to handle more batteries being charged. Haven't done this protoype setup yet to see if it works or not...

Look up the specs on the BLUE SEA SI-ACR smart relay shown in the drawing
