I have a 2021 Thor Sequence 20K built on the Ram 3500 chassis. Everything was working completely fine but today when I got in to start up the vehicle, my radio and backup camera is not working and the odometer on the dash keeps flashing and when I put it in reverse it does not make the constant beeping noise. It's just too little tiny light sounding little beeps and it's completely different than what it should sound like. I haven't checked the fuses or any breakers yet but wanted to put this post out there to see if anyone has any suggestions as to what may be the problem. Has anyone else had this happen?
