I have a 29M, mine is a 2018. My DW believes in bringing everything imaginable and after loading and weighing we are hundreds of pounds below the max axle weights front and back. I wouldn't worry about the CCC of the coach. I would be more worried about the lack of build quality that is endemic across the Thor Industries product line. Yes, all coaches have issues, but the folks that build Thor coaches have to be the least trained and qualified assemblers in all of America.
