Not sure of the true engineering aspects, but in general, rear-wheel cars have more traction, creating more power for towing (push vs. pull). Since SUV's are supposed to be for pulling, towing, off-road etc (not towing babies and groceries) then this would probably be the reason.
Front-wheel drive was created as a cost-cutting measure - the ability to put the engine, transmission, steering, front suspension all together in one assembly and bolt the whole thing in the car. With 4x4 such an effort is defeated by all the mechanicals related to the transmission that have to go elsewhere.
Also, as Sccutler mentioned, FWD is not designed for loads. I've never seen a FWD Semi-truck.
