Recomendation 3:73 VS 4:30
Trading in my 06 6.0 pretty soon for the 2012 SD 6.2. Really like what I have been reading in this forum about the 6.2 SD. My primary towing is a 5000 lb. tractor, 500 lbs. in extras and trailer weight of 2300 lbs. My towing is generally in flat land to some foothills. Neither of the two dealerships have the 4:30 in stock. I understand the differences in the two rear ends, just want an idea of what would be the better choice for my circumstances. This truck is not my daily driver. The chance that I would ever be pulling over 10,000 lbs. is remote. Both trucks I have seen so far have 18" wheels. Thanks guys for any advice you can give me.

I think its going to come down to how often are you going to tow. I have the 3.73 gears and i plow with a 10 ft plow with a spreader all winter no problems ,, i tow my 33' travel trailer thats 7600lbs.in the truck 2 adults 4 kids 2 100lb labs in the bed ,, and im doing 65-70 mph with no problems 5-6 times a summer ..

Thanks for the input. Most of the time, if I am using the truck it will be for towing the tractor and attachments. I am thinking about geting a plain Jane work truck or just a XLT trim since I already have a daily driver and the wife has an 08 Tahoe. Seems like the choice is for the 4:30 rear end which means the dealer will have to searh for, or order. Anything else I should think of as a must have optio?

Since you are a flat lander and that is all the weight you are towing my "guess" would be that the 3.73 would be the choice.
I just completed a test pull with the 11500 fifth wheel with the 4.30. Windy day. Down wind pulled in 6th effortlessly. Up wind it spend quite some time in 5th.
I got the feeling I am gonna sit back and relax when I hit the smokies this winter on my way to SC.
