Destin, Florida Salt Air Damage

We have had 5 different RVs over the past 40 years and often camp within 20 feet of the Pacific Ocean for 3 days to 3 months. Plus our RVs are stored about 6 miles from the ocean when not camping. Each has shown some rust on the frame but chrome and everything else doesn't seem to be affected.

I do rinse the RV off once we bring it home after staying at the beach.
