LBZ oil pan

[Odlaw]

I thought I read about the oil pan on these trucks somewhere on this forum but search turns up nothing.......so, while changing the oil in my d-max this weekend I noticed (again, but actually made a mental note to discuss it here) that the oil pan straddles the cross member between the lower a arms and appears that the front of the pan drops down farther/deeper than the rear of the pan(where the drain plug is).......looks like it should have a drain plug on the front portion too. What is the deal with this?

Thanks

I noticed this too, when changing the oil. I am not sure as to why GM did this, but I counteract that by driving the front of the truck up on ramps. It gives me a better drain.

Lots of aftermarket pans have this too, I would think there's something internally that would direct the oil out. They do changes at the dealer on lifts, so it's not like they didn't expect it to be an issue.
