I had to haul a load of fitness equipment down to San Jose on July 1st. Hot miserable day, about 9500 lbs dragging behind me. This towing twins setup still amazes me even after a year. I have to watch myself going up some of these long grades like Altamont pass. I'll be cruising along at 70 or so if i don't pay attention. Coming back over with just the trailer i went around a couple of trucks and hit an easy 80mph before i realized it. No egt issues, no water temp issues. Now if i would just quit screwing around and get my air conditioner up and running it would be perfect. Best part is the funny looks I get when you pull along side a brand new truck pulling a similar load at about 55 up a long hill. You start pushing down on the pedal and the turbo whine starts letting him know that the old first gen Dodge is about to leave the area. It's always a good idea to get well out in front so they don't see the look of terror on my face trying to slow it down on the long downhill. No doubt about it. My ability to pull has risen faster than my ability to stop. I need to work on that.
