re: Best way to protect an RV frame in Grand Isle?

Ours isn't under a cover, but it's on a limestone driveway (sucks to have to crawl under it in limestone).

I noticed that the top of the main I-beams where it was protected by the aluminum siding of the RV was in good shape, and the bottom of it had alot more rust. I think a skirting from the ground to the top of the I-beam would help alot also.

Seems like WD-40 would be too thin to last. That's why I've heard good things about transmission fluid.

And I'm removing the stairs and bringing them home. I have a 6x5' deck and stairs that I put in front of the sliding glass doors and wooden stairs for the bedroom door.
