I have never been on soft sand with my Jeep Commander. I loved off roading in northern Michigan on some back woods two tracks, but I am a little scared to take it to the dunes off lake Michigan. I always hear stories of people blowing their engines or trans out there. Also i have stock 245 65 17 tires and I'm afraid of getting stuck and making my baby look bad. I'm sure the Jeep can handle it out there but was hoping some one had some experience on sand dunes.
