Two very simple things. I would not take it back to them as IMO, it will sit in their shop for a very long time. That they did not fix it correctly after having it that long tells me they either don't care, are inept or both. I would file a complaint with the Bureau of Auto Repair of Nevada and have them intervene with a claim. They will need a copy of the bill from Freightliner/Nevada as well as the repair bill from whatever facility you end up taking it to. Massy's is well documented and known for excellent repairs. Finally, be sure to post your review on RVServiceReviews.com so others are aware of your experience.....Dennis
