Advantages of a unibody???

[ChevyKev]

I think when Jeep wanted an suv which could still offroad like a waggy and fit 5 people but drove more like a car the uni-body was the creation. Less truck, more car, still Jeep, and thus the "soccer mom was born"

Here I think is the real answer to why - underlined in bold.

More car like handeling + less cost I mentioned earlier. :whistle:

I think it is a great product for it's design, heck I own one too, but to be built really big it does need attention, as all rigs have their shortfalls.

Absolutely. As well, I agree that they do well for their design, until you build them "really big"
