Protecting BB in Aggressive Salty Beach Environment

[Henry Claeys]

I've got an aluminum framed, fiberglass skinned, 5th wheel parked about
200' from the ocean and it's holding up pretty well. Problem is that
anything metal rusts and I'm constantly treating and/or replacing things
so that they are more salt resistant. I'd love to park my Bird out
there, but fear that the salty air environment will ruin it. I can wash
the exterior, but how will all the other parts hold up, like the engine,
frame, trans, brakes, cables, generator, etc. My old van has picked up
lots of exterior rust even though I wash it. A couple of years ago I
read about ocean going ships attaching magnetic devices to their hulls
and protecting them from rust. If ocean going ships find the results
effective, then maybe it could be adapted to a BB? Any creative ideas?
Thanks,
