The warranty says 21 days for repairs.
Call Thor and get them involved. Inform Thor that you are sending a letter informing them of the problem and then send the letter. Once they receive the letter (which serves as official notification) Thor has one final attempt to correct the issues or buy the unit back less depreciation. Once Thor is officially notified it then becomes their problem.
Also, go to
RV Service Reviews and post a review about the Camping World service department so that others using the service can be made aware of the issues.
