I would not leave it salted , try to rinse it off as suggested, if you can, remove the camper and take the truck solo to an undercarriage car-wash . If you park it in the sunshine, it should dry itself.
My experience in traveling up to Coos County is the truck taking most of the hit, the undercarriage . I try to use my truck from time to time (on dry roads) just to keep the rust off the rotors.
As far as the camper goes, the rear skirts take the brunt of it.
I caulked the skirts around the molding trim where tire road slush accumulates plus I installed large mud-flaps to keep it at a minimum .
These are the areas I concentrate on when I rinse the rig using hot water (I installed an outside hot water spigot on my house)
Someone here mentioned they use a garden sprinkler under the truck and that works well. I thought that was a good idea so I do that now. Thank you for that idea .
