I got a 4door 2wd stock explorer and i have been through some really rough mud. my buddy had a jeep with 44's and the mud was over his lugs and he wa crawling through. I tore through the same pit 6 times with out getting stuck. Its all about how you drive. Don't go through a rut made by 50" tires...you will just bottom out. Keep up your momentum and you will slide though...Dont start off crawling in...start with some speed so if you high center you will have a chance to slide over and get to a shallow spot...If you have a feeling there might be rocks or trees in there don't romp through it....i am in such denial... has anybody seen the truck called wild horse??? look it up on youtube.... just drive like that guy youll be fine!! 4wd is boring go 2wheeel!!!!!
