Thinking about installing a 60a dc-to-dc charger in our truck camper. Have plans to power it with the 220a alternator in our truck.
How big is your current alternator ? It is probably sufficient to power a 60A DC-DC charger.

Also have a question about how most DC-to-DC chargers operate.
Without getting into too many gory detail:
• Incoming DC is converted to AC by switching it on and off. This is done much faster than the 60Hz that we get from the power company so that they can uses smaller transformers.
• The transformer boosts this AC voltage to something higher than required to charge batteries
(18VAC-24VAC ?)• This AC voltage is converted back to DC
• Some kind of "smarts" controls the output DC voltage to the appropriate amount.
