You don't want to be putting stainless bolts on your galv trailer unless you start adding isolation between the metals, you will accelerate the corrosion of both components. Go for galv.

A2 (316) austenitic stainless or 300 series.....the electrolysis effect will be minimal.

I think you'll find A2 are 304, A4 are 316. You are correct in that the corrosion will be minimal, but what happens in a salt water environment, is the "minimal" corrosion compromises the galv around the stainless fixing & allows salt "into the wound" the galvanised metal will rot under the zinc causing the zinc to spall off. As I said, galv to galv, stainless to stainless , never the twain shall meet.
