Drove from Gibson Louisiana to Abita Springs Ocean Canyon RV park. Upon arrival we had a buzzer alert going off under dash, we then parked to RV. Tried to put jacks down, did not respond, tried 12v lights did not work, tried slides, again no response. We then plugged in and were able to get jacks and slides out, some lights worked. Still alarm under dash, checked 12 coach battery, almost dead. Called a mobile RV tech, 2 1/2 hours later, he found a ground bolt had come off with 3 grounding wires on it. Tech advised that bolt was only tacked on one side, my Warranty company said a original technician fault and not covered. Talked to Thor later, they advised that is how it is attached, advised warranty company and they still denied. Told Thor that was very poor workmanship for a company trying to improve their standing. This cost me $358.05 out of pocket and time from Rving.
