Well after we stopped to eat Julie and decided to head down to town. Julie's neck was beginning to hurt. Good thing as we headed back down through Apex our truck started to over heat all the way back to Denver. Temp would go up and down and while airing back up it got pretty hot. I noticed that the fan didn't seem to be running as fast as it should be. So I am thinking fan clutch possibly. If anyone else has any ideas let me know. So I am sure that Alex and Nate are probably getting close to finishing the trail soon at this time.
