I have a 2005 SR5 Pre-Runner 2wd and I am looking for the most efficient way to improve my off roading. I do not plan on rock crawling or driving in the snow or any other extremes. But I do enjoy some of the average trails and riding in the desert. There has been times where having rear lockers/lsd/4x4 would have been helpful. For the most part, I click the emergency brake in about 2-4 clicks and I usually can get my self going.
So I am looking for any recommendations on how to improve my truck effectively without being out of this world expensive.
