Anyone seen the Dodge pulling 17,500 trailer up the Gauntlet. Man if it struggles with this weight no way it can pull 30K. Im a Dodge guy but i think none of the big 3 could tow up this grade.:)
If your talking about the I-70 Ike, I had no problem with it with my rig a few years ago. It down shifted like it should, I forget the exact mph and rpm now, but I passed an older Chevy 3+3 crew cab with a slide in camper and a small tow behind trailer. I assume it had 454 gasser so not surprised. Tranny didn't get hot nor did the engine. I was right at 19,700# combined weight. I am a happy RVer.
