The MorningStar SunSaver Duo doesn't have a diversion mode that is needed for wind power. The Tristar C-45 is a good choice but is more costly than the Xantrex C35/40. The Xantrex C35 is around $100, Xantrex C40 around $125, while the Tristar C-45 is about $180, all prices are without meter. I guess it depends on how many solar panels you plan to add, and if you're mobile or parked for good.
I've been running my 27ft travel trailer on four marine deep cycle batteries, charged with a Xantrex C35, from one BP 80watt panel and an Air-X. Its been up and running for four years now with no problems.
