I've just ordered a F250, V10, CC, 4x4, LB with 4.30 LS diff. I live in CA, so the 3.73 LS was not an option. I'm not going to be towing anything drastically heavy, so should I have gone with the 3.73 without LS? Is LS necessary? I heard that since I'm getting a 4x4, I should have LS.

Thanks for your input.
