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...

You don't state what type of truck or the system voltage. In theory, you could use up to 100% of your alternators capacity to charge your batteries but IMO, that would not be a good idea because your truck needs some of the alternators capacity for "other" electrical consumers too. Chances are that your electrical system is under sized to run more that about 30/40 amps to your batteries on a continuous basis without locating its weak link for you. IMO when OEM's call out an alternators specifications, they mean MAX, not continuous.
