Hello! I am driving my SP down from British Columbia Canada to Phoenix this November to spend a few months in your beautiful part of the world. I know we will hit snow on the way down from Canada as we will be going over some high mountain passes. Can any of you knowledgeable folks recommend a place in the Metro Phoenix area, where either (ideally) I can self/bucket wash it myself, or failing that, a touchless drive through car wash that will soak the heck out of the underside to get rid of all the salt and other crap I'll have pu on the drive down? Many thanks in advance for your advice!
