We ran a 475 C-15 in a tridrive/tridem trailer configuration grossing about 118k in the BC mountains. I think you're kidding yourself that 450 is inadequate for a measly 84k. The 475 wasn't the quickest up the hill but it held its own. The guy with the Signature 600 with the same weight and setup could pull the hills about a half gear higher.Last edited: Jun 28, 2019

Most drivers couldn't feel the difference between a 475 vs a 550. 475 pre-low NOx beats a 550 low NOx any day of the week.Diesel Dave and AModelCat Thank this.
