features for dc to DC chargers

Been some threads on this. One thing that came up was to have one that is buck/boost where some new charging systems let the starting batt run too low at 12.x and at times it is too high at 15.x.

They are programmable, so the first thing is to know what you need yours to do, then see if a particular model will do that.

My main concern was amperage. Enough to run my slides. But, mine's just a converter.. I'm not sure I'm talking about what you're talking about.
