Sure it would be repaired, but only after they knew they had a sale, and it would be on your time more than likely. That's how it's done. The manufacturer does a bad job or an incomplete job. The Dealer accepts it when it's delivered. The dealer then submits a warranty ticket once they sell it so they can get paid to repair it or finish the build. Where the buyer gets screwed over is if the repair requires parts and the dealer does not provide them or the factory insists on providing them. Then it may take weeks or months. The dealer will probably try and get you to take the unit and then return at some point to have the repairs done. By then the buyer is at the back of the service line as warranty repairs pay the dealer less than an off yhe street service customer. Good luck with that.
The RV Industry is rotten from the top to the bottom.
