We've always had a boat, so our truck is in/out of salt water all the time. Our wheels are not the prettiest in town, and we often wonder how folks with newer trucks manage to keep them so shiny. In our defense, our truck is 23 years old, no spring chicken. I don't know about just parking close to salt water, although I imagine it would make sense to keep your rig washed and waxed on a regular basis, both for the salt spray and also wind-blown sand. Which reminds me, Anna, are you still pleased with that washing system you bought? I think about that at odd moments.
