Hi guys - I've owned a 2007 79 series V8 from new, and while we don't do the sand driving like in other places in the world, I cant fault the drive ability of this model over the old 70 series. The old model was great, but this model does everything the old model did - but easier and it feels better doing it. Much more stable truck while undertaking any sidling, or anything on an angle, great visibility looking over the front. Done a lot of 4WD in the last 7 years, and the difference in track has never been an issue. Yep don't look great when following from behind - but it does not seem to affect handling etc at all. Thought that may be useful. The only thing I've changed is the Tyre size to 285/75 16s, BFG MTs. It gave the truck an 50mm lift.
Hope that helps
