Jon, I 2nd your thoughts about the trans retarder, I am now up in Yellowstone and this is my first trip with a 17000LB trailer, try slowing this without toasting the trans fluid. I own and have driven 80,000lb trucks with jakes and I for the life of me can not understand why some SOB took the jakes away and used this retarder(retard)! And I was told the retarder cost way more than the jake's, now I know why.
