I ordered a Progressive Dynamics (PD9270V) having "iCharge Wizzard" Don't know how it will fare on tapering charge to meet battery condition, but the marketing department did a nice job on the words. They list this one for wet cell and AGM, and had another for lithium ion. I think the coach was set up with this along with a stand alone inverter, Xantrax Power 3000 plus. If I find a better maintainer in the future, I will change in a heartbeat. These are just a fraction of the cost of replacing batteries.
