If your just looking for a charger, I've had good luck with progressive dynamics models (pd9180 etc.), thats an 80 amp unit. Iota and xantrex make excellant converters as well. Basically a "smart" three step charger; consider getting one with some sort of remote control. Xantrex, then Iota are probably more expensive. The Xantrex has a built in bank isolator which in some instances can be usefull, but only a 40 amp output.
If you need an inverter (110V output off the batteries) then you'll probably go with the Xantrex. Most of these have a large battery charger built in. Such as the prosine 3.0; expensive...

Make sure you have good grounds between all components, engine/alternator, batts., and chargers. I had same problem years ago and found bad ground between chargers and batts.
