Greetings from the Florida Panhandle
We live three houses off the Gulf of Mexico in the Florida Panhandle. Our Airstream stays in the alley behind our house when not out traveling. We have had three Airstreams over the past fifteen years. Being so close to the ocean can be a little rougher on the Airstream, but ours is in this environment 200+ days a year.
I don't think you will have any problems camping near the ocean for a week or two. When you leave the beach, just stop and rinse her off at a car wash to make yourself feel better.
