Well, I have an update for you.
The dealership found the welder to fix the cracks. I met him yesterday at the dealership. Right in front of Steve (our salesman) from the RV dealership, he said it was the worst welding job he has ever seen. He said the reason for the cracking was overheating the metal. This is exactly what everyone that I have shown the pictures to have said. The welder told me how he will fix it and said by the time he is done it will be 10 times stronger and will never be compromised again.
Steve's position was the same as everyone else at the RV dealership, they all said the welding was good and the cause was potholes and/or bumps in the road. Now they are taking a different position and they will be contacting Northwood with the NEW FINDINGS.
At this point I hope Northwood will take care of the costs. If not, I'll get an attorney. An attorney might say based on the welding that the trailer is not safe and tell Northwood to give me my money back. It's not what I'm looking for, I just want it fixed right.
