Using a charger instead of a converter means using the batteries until they get low and then recharging, repeat.
A converter will stay on at 13.6v and run your 12v loads with no draw on the batteries, so that is what you want. It can also act like a charger when required to do so.
A "trickle charger" that stays on constant voltage at low amps would be ok for storage time battery maintenance, but while camping the low amps means it likely can't run the 12v things in the rig all by itself, so the batteries will still get low.
Therefore you want a converter with enough amps. AFAIK, this is the lowest priced one that can do the job you want as long as your total expected 12v draw at any time for a mix of 12v things is under 15 amps. $87 and free shipping:
