This difference is typical. And my rig, a 2006 3500RL with a 2005 floorplan showed several inch differences for the SAME year, depending on what document I picked up, so from year to year, why not. I just say I'm 37' 6" and cover all the possibilities. More times than not being over is not a problem, but being under can be a problem.
Things impacting these differences: Ladder, measuring to the nose of the rig, measuring to the pin, measuring to the front of the pin bracket, mood of the employee making the measurement or just relying on blue prints per year, and the variances go on and on.
Like you mentioned, weights are even worse!
Good job on going for the bigger truck!
