I think the 6.2 3.73 works out well unless towing really heavy in the mountains. If you tow at 60-65MPH, 2nd gear will put you right at peak power for the hills and also has some headroom for passing(70MPH @6000RPM). The 4.30 can only downshift to 3rd at 60MPH and is nowhere near 385HP when stuck at 4000RPM.
hopefully I'll be happy, I've done a ton of reading and it seems guys towing 10k+ are still reporting great results with the 3.73's and I'm only ~7500lbs wet. guys pulling 15k fivers all say go 4.30..which is understandable.
If I was worried about the possibility of getting a larger trailer in the future I would definitely order one with 4.30's. but I only tow ~10 times a year and our trailer is only 2 years old now and the kids are 12 and 15.... so eventually they will grow out of it and it will just be my wife and dog....so we will only go smaller with the trailer.
