I live in Oklahoma. I don't rock crawl or get into much sand. but I find myself in mud quite often. My question is, i am looking at 07 Toyota Tacoma. 4.0L V6, 4X4. However, it is not the TRD package so it does not have the locking rear differential. I have heard it makes a big difference on 2 wheel drive trucks, but do you think I will miss it on a 4 wheel drive truck? Some say yes, some say no. Opinions?
