If I were you I would definitly put it in the front. A locker will help you in any off road condition. As I see from the left, you have a pickup, meaning most of the weight is in the front under the engine. Front tracktion, i think, will actually help you more than in the rear. With manual hubs, you will not notice the change at all on the road. If you were to put the locker in the rear, your truck would scuff and chirp the tires around corners, and maybe even make the truck hop. Long story stort, I would, and I am, putting the locker in the front. Also, later you could maybe put a possi kit in the rear so you have all wheel drive. Just a suggestion. Help all this helps.
