Lots of good chargers out there. Not sure about the three-gang part, but we're using a Progressive Dynamics 70-amp multi-stage charger with great results. Here's a link to the info page: https://www.progressivedyn.com/rv/power-converters/pd9200-series-rv-power-converters/pd9270-70-amp-rv-convertercharger

We got ours on Amazon, but there are a number of places selling them. They also make a smaller model if you don't need 70 amps. We're using the 9270 since we have about 780 Ah of capacity and Trojan recommends about 10% charge rate.

If you don't need the three gang feature (simultaneous charging and monitoring of three separate battery banks, common on boats but not on buses), then there are a ton more available, like the one mentioned above.  I usually buy from this guy:  http://www.bestconverter.com/
