the V8 is not AWD. its full time 4 wheel drive.
I don't think you would see any difference in 4wd between the two. The nice thing about the V8 is more torque.
V8 also has the more updated 5-spd. gearbox. I got mine for invoice and price wise it was less than $1000 to go with the V8. So WTF? I got it.
.
Also the V8 has 4 wheel traction control (TRAC). The V6 only has rear wheel traction contol when in 2 wheel drive mode. Kinda off subject but somewhat relevant nonetheless. Which brings up a good question. What are the everyday differences between 4 wheel TRAC on the V8 and H4 4X4 engaged on a V6. Any comments?

And the V8 has the weight distributing hitch and not the weight carrying like on the V6. (some other small differences.)
