Before I clicked on this, I thought for sure the dealer would turn out to be a Camping World. Surprise, it isn't!
There are supply problems for some parts these days, but who knows. You should definitely call the dealer. If you don't like their reason for not getting it done, tell them you're coming to pick it up in X number of days, whether it's fixed or not. They can't make money on work not done.

Liberty is meaningless where the right to utter one's thoughts and opinions has ceased to exist. That, of all rights, is the dread of tyrants. --Frederick Douglass
