Our 08 F-250 came equipped with traction control. This works ok but I'm concerned that we'll still get stuck in a soft/wet pasture. (4wd on soft ground with open diffs = one front and one rear spinning wheel). And it will also help when getting around on winter roads.
I'm thinking about installing an Eaton True-trac in the rear. Has anyone done this? Did you feel it was worth the $800?

You sure your truck doesn't have a limited slip rear diff.?? I got a 2010 2500HD GM with traction control as well as a locking rear diff. Got your truck's window sticker handy?

Ford offered an Open, a Limited Slip and new in 2011 a Electronic Locking rear end.
I've never had the open rear ends. I have had serveral of the limited slips and still felt like I needed more tractions. Too many job sites are real muddy in the wet months and when I backed in and would still get stuck having one front and one rear tire spinning even with the limited slip. So I opted for the electronic locking on my 2011 truck.
I am learning that there are pros and cons to locker as well. If I'm on any kind of side hill and engage the locker, the truck has a tendancy to slide sidewize when both rear wheels lock and begin spinning. When I forget to turn the Locker off and pull on good traction, the truck bucks and I wonder what the heck, until I remember to unlock the rear end.
Its a $390 factory option, So $800 for an aftermarket is not unrealistic price.

I have a true trac in one track and the ARB in the other truck. The true track is very nice, I do like being able to turn the arb on and off as I please plus it is a full locker.

From what I hear, the true-trac (torsen) offers more torque than the average factory clutch-pack limited slip. The reason you don't see them as often from the factory is cost.
Lockers obviously do the best but I suspect that's overkill. We expect some mud and snow but not rock climbing.
