Billc, I read your post and almost laughed until you corrected yourself. I laugh at what some folks call mountains. If your ever out West, try the grade up Donner summit on I-80. Or perhaps if your in Colorado try the grade on I-70 into Denver. I live fairly close to the Donner summit, when you come down it, you can look at the the trucks (semi's) and see some cherry red drums with smoking contrails pouring off them. One day while driving to Tahoe, I saw a brand new Dodge Cummins Turbo Diesel Magnum Dually raahhhhh, on the side of the road. He was at one point, pulling a 6 horse 5th wheel trailer. Something went wrong as the truck was completely upside down. Funny and fortunately, the horse trailer was upright but still attached to the the bed of the truck. It was as twisted as you can get. To this day I still wonder what happened to them and whether there were horses in the trailer. It looked like a case of the truck telling the trailer to follow me and the trailer saying , no, I think well go over here. Oh yeah, my point being, was he using Amsoil? Rat...
