Stick weld aluminum

[Mark @ Everlast]

Treat it like you are shaking the water out of a garden hose end after you turn it off.

Thanks Guys,
I think I will look real hard and using steel frame for the winch mount and then bolting to the aluminum with mylar insulation between the steel and aluminum.

Using an epoxy adhesive as your galvanic barrier is an excellent option if you don't plan on easily removing it.
