Tiger Truck anyone?

This gives perspective to their size:

So this model is the largest and not street legal?

I think the lack of being street legal is not as much about size as it is about noncompliance with safety and emissions laws. Besides the usual (seatbelts, airbags) there are also requirements for side impact beams, rollover crush tests, fuel tank integrity, and so on. It may be that the company just doesn't think the cost of upgrading to meet these standards would be offset by sales enough to make it worthwhile.
