Pin weight ratio

[LERD]

I have done multiple searches for this question, both on this site and the Keystone site and I'm still not sure of a definite answer. I do not have a Monty yet, but the DW and I like the 3120rl the best. The published weight is listed as 11999 lbs empty and a pin weight of 2350. That gives me a pin weight ratio of 19.6%. So my question is, when I am at full capacity of 16k (which may never happen as we will be longtimers not fulltimers) will that ratio still be the same or close? I know that it's not an exact measurement, but for those of you that have scaled your rig in full combat ready mode, has the ratio been the same as empty? I'm a Ford guy and the DW wants to keep the TV to a SRW. So I know that I wont be over on the GCWR with either the 6.7l or the 7.3l engine. I trying to find out my margin of error on the pin weight. Thanks for everyone's help and advise.
