Alternator: How many batteries can it take?
I have a diesel, so two batteries for truck, there are two 6-volt for the Truck Camper, and I want to put a deep cycle battery in the cargo trailer. The Camper does have 200 watt solar to charge it...

Assuming the non-starting batteries are 6V deep cycle golf cart batteries and they are at 50% SOC and you have no DC-DC charge controller, the answer is several days !
This. If you're not going to also invest in a DC > DC charger such as a CTEK 250SA then you're wasting your time & effort trying to use your truck's alternator as a source for recharging depleted deep cycle batteries.
