In my case I just went with AGM. No more water checks or corrosion.

I was surprised and disappointed to discover corrosion on the terminal of a lightly used AGM battery. (Positive terminal only)

I'd expect that when the wire was tightened on to the post, it was over-torqued. I had a Lifeline do that and they was replaced it with a new one. We've had 18 Lifelines in 3 different coaches and other than the problem I stated, we've NEVER had any corrosion. Blow them off once or twice a year with the air hose and good to go.
