Can CCC be increased by making alterations to a Cameo 5er?

Here are some numbers to consider...

2009 2010 2011

dry axle wt 10,425 10,620 10,305
hitch wt. 2,825 2,630 2,900
dry wt. 13,250 13,250 13,205
CCC 1,749 2,749 2,749

Let's see if someone can see any patterns or correlations to the mystery at hand! It's like rubik's cube!

Gee! I configured everything into a nice chart form, and the configuration completely disappeared when I hit "submit!" Hope you can make sense of the numbers!

The 3 sets of numbers are according to the years listed above them.
