wow, kinda a harsh crowd in here. i use the truck for daily driving and would love to take it mudding all the time but i don't always have time to do it and don't know all the places to go. i bought the truck with the 39.5's and the sas done already. with the d44 and d60. it works just fine for me and has worked great in the couple times i have taken it in mud. and i havn't snapped a axle from that either. i deff. am not building a rock crawler, its just a big truck that i can use every day and take it out and have fun with it also. until i finish my blazer then i wont be doing anything crazy with this truck. thanks for the compliments for those that did....
