There are a couple of car washes that I can get my dually in. Have to make sure that it is one of the 'touchless' car washes. The kind that you drive in and the power wash nozzles move, not the truck. They won't let you in, nor will it fit in the ones that have brushes. I use the touchless near my house in the winter, as its hard to wash at home when its gonna be 0 degrees this weekend. It doesn't do that great of a job, but it gets me by until april.
