I have one of those 2.5 gallon water fire extinguishers that you can refill at home. It takes about 2 minutes. I fill that up with water and "Salt Away" and keep it in my truck to rinse the brakes, wheels, and trailer as soon as I am done launching my boat in salt water. It works on the boat, so I am sure it would help on your truck. It also leaves a protective film behind.
I know some of the guys who surf launch dories in Oregon, use garden sprayers with a diesel and oil mixture to pretreat their undercarriages. That sounds like a mess to me, so I'll stick with the SaltAway.
I plasti dipped my wheels last year and it has held up well. I don't know whats going on under the dip, but it looks like new on the surface.
