When GM wants to increase tow rating numbers they will add a 4:10 axle to their list of options.
I second that the transmission has been the issue. My motorhome also uses the Allison 1000 transmission and is limited to 30,000lb GCW. Freightliner has told me that the transmission is the weak link. I have looked at the Allison website and they confirm that rating without specifically mentioning the GM version of it.
It seems like I have heard that the 2020 GM HD trucks will come with the new transmission co-developed with Ford that seems to be working well with much heavier loads.
