Gofast, I haven't really done any trails. Were I live at there are no trails. I climb hills in mine. I only problem is I keep dragging the bottom. One time I made it to the very top of this huge hill, it went straight up at the very top. I just spun, so I backed back down a little and went a little faster, I spun again. But, I didn't back down. I went even faster. The bottom of my explorer bounced on the rocks like a basketball, but hey I made it up Dead Link Removed I haven't seen anything that my explorer won't go up. The only thing stopping it ground clearance. I dont' take it out in thte mud because my dad doesn't know that I do this ind of stuff, he'd kill me. So I keep as much mud off it as possible. Me and my brother race all the time. We tie on take off, but on the interstate, like I found out today, I totally outrun him. I have a 3.07 rear end, he has a 3.73. That's why. I stayed beside a Plymouth Neon Sport. It had about 170hp he said. He did an air box modification. I stayed beside him until my explorer shifted into second gear at about 50mph, then he ran off and left me.
