Was it a case of old school mentality in a modern 4wd.

Seen plenty of people add items just for the sake of adding them.

Havent had my D3 in a situation where lockers were needed, but my standard D2 went all over the place and only ever got stuck once. After seeing the pics of that area when it dried out i would doubt any amount of lockers would have got it out.

What ever floats your boat i guess.
