No, everything including the frame, interiors, suspension, everything is different.
The US truck is a totally new truck, has nothing to do with the international one. Chevrolet tried that with last generation corolado, even a V8 could not help it. they learnt their lesson.

In other words, GM built another unique truck for North America with limited scale of economy
and moderate investment into what could be a relatively small market.
Toyota does the same with US Prado based Tacoma and International Hilux so I suppose
if it's done properly, it's simply a cost that must be born to fill two different markets.

The United States is not a small market and this truck is a part of their overall truck strategy. Its entirely possibly their are reworking the diesel for US duty too.

The mid sized truck segment is comparatively small when Toyota, the segment leader
with little competition barely achieves 12,000/mth sales. GM spent a lot of money to
get back into this segment with a dedicated product, let's hope they made the right decision.
