Sounds like your dealer took good care of you as soon as they realized the mistake. Sometimes one mechanic isn't familiar with all the details of an installation and does it the way he/she does it with other brands. That's no excuse, just life unfortunately. I'm glad to hear that things were corrected, though, and things are like they should have been to begin with. Now you can tow with one less thing to worry about; monitor yes, worry about, no.
I know that since I have read about brackets falling off I'll be monitoring mine just to make sure it doesn't happen.
