You can get it in 4x4 in the US. And it looks like I didn't dig deeply enough I selected the HFE version which is 4x2 and standard cab only. You can also get the Penstar in the SLT which allows for Quad Cab and 4x4 versions.
I don't understand their packages. It seems like the SLT gives you a bit more in features for about $1000 less. Plus it comes in the Copper color I like but the HFE doesn't.
