I think you can tell we have a few rabid Trooper fans here.

What it boils down to is if you want an SUV that is as much like a LUV as possible, the Trooper is that SUV. I've been so happy with mine I'm looking for another already. Thinking about getting rid of some of my wrecked/rusted out parts LUVs to make room for parts Troopers even.
They really are capable offroaders right out of the box. The 12 bolt Isuzu rear has been described as "somewhere between a Dana44 and a Ford 9 inch" for strength, never heard of anyone breaking one actually. The front IFS is still pretty weak compared to a solid axle, but able to get banged over some serious rocks before breaking a CV or half shaft.
