I have started out contacting Thor via email at least 6 or 7 times in the past 18 months and I have gotten responses, action and call backs after every time I made contact.
If it was me I would send a well documented email..... dates, times, places, pictures, issues, etc..... and your VIN number and I would be very polite and ask for help after the dealer failing you for the past 12 months.
I’d bet my next payment you get a response and a good experience from
It.
Here is the email address:
