Our routes sound similar. Clearly, were headed into the corrosion zone, and I've been there many times. I'm far more worried about corrosion on things like the frame, the gas tank, the suspension, actually... pretty much anything metal under the van, than I am about the frame horns. My regular plan is to wash the undercarrage as often as possible, normally at the end of each trip. In the spring I treat as much rust as possible with some type of conversion product and then paint. Rust is going to happen no matter what we do, the trick is to stay slightly ahead of it. If an isolater pad helps a tiny bit, or provides a miniscule additional amount of impact force absorbtion, I see no reason not to run them if you want to, but personally I don't think its a big enough difference to matter much.
