Rick is the GOAT. I don't need truck repair very often but when I do, KnM is easy to work with and they have always done the job right the first time.

Rick knows his stuff as well as his guys. Great shop. You may have to wait your turn... they are well known for skill and can be overwelmed with customers. Always a good thing for them.
