This was ripped from the 4x4wire.com forums:

No Thailand SUV, no surprise. I've seen that thing in person, and it's not suited to the US market: high ground clearance, decent a/d angles, a sweet turbo diesel engine, body-on-frame, skid plates, LSD, and many other 'functional' niceties those who actually USE their 4WDs can appreciate.

Perhaps if it was unibody, had a piggish V8, frequently broke u-joints, lacked underbody protection, came with a sluggish automatic and no LSD, but had fantastic cup holders and a DVD entertainment system, we'd see it in the US.
Can't say I disagree.
