What's Your Lowest Uphill Speed And Gear On I-90 From Spokane, WA To Missoula, MT?

I was assigned with a 2012 Volvo 670, D13/AT2612D ENG/TRAN combination, when I was there with 42,000lbs of load behind me, I was getting 30mph under 6th gear(out of a 12-gear tranny!), barely crawling up the hill. That is one of the reason why I wanted to get me another truck.

What about your truck? Please have these information given if available. Thanks! I'm taking the uphill ability of a truck very seriously.

Truck brand, model and production year, Transmission brand and category, total of gears(eg: EATON FULLER 13 SPD), Load weight, Lowest speed spotted and gear in use.

Whether you're talking about 4th of July Pass or Lookout Pass, it's not the truck. No truck in creation is going to fly over those hills with 40,000+ in the box unless you strap a rocket booster to the roof. If you're still doing 30 at the top of the hill, you're ahead of the game.

I remember going over Lookout Pass, heading to a camping spot near DeBorgia MT, in July, and it was snowing so hard we couldn't see a thing. When we *finally* made it to the campground I thought I'd kiss the ground. This was just in a 4 wheeler. I can't imaging going over those passes in a big rig in bad weather.

You should feel lucky. I would be doing 22mph in 6th gear. DD13 doesn't have anywhere near the power that your Volvo has.

Completely agree with Fatsquatch!

These trucks aren't designed to fly up these steep grades, as a rookie I know it seems like it is taking forever to climb a hill, and you are probably wondering why other trucks are passing you. For one thing, as a company driver, you are probably in a truck that is governed, which means the amount of fuel that you can feed to the engine is restricted. That alone will hinder your ability to gain much speed on a steep incline. The other thing is that you don't know how much weight is in those trucks passing you. I drive a Volvo which is set up similar to yours and it outperforms many of the other trucks I have driven. I think you are just not accustomed to the reality of what it takes to climb these grades just yet.

There will always be the smaller trucking outfits and the owner operators whose trucks are not governed passing you on an incline - get over it - don't be thinking you need a new truck every time somebody passes you.

LMAO. Old School, you nailed it! Hands down! LOL

I drove through mountains for the first time last week (Appalachians) and found out very quickly how LONG it takes! 30 mph uphill, and I was extremely cautious downhill, so everyone - even the Prime trucks - were passing me! That poor truck was working so hard to pull 42,000 lbs. up the grades, just could not go any faster.

This. This right here. It isn't a d*ck measuring contest to see who can get up the hill the fastest. It isn't (or shouldn't be) an affront to your masculinity if someone passes you.

It just makes me shake my head how many guys base their manhood on whether their truck is the fastest, the shiniest, the most stretched-out, or whether their radio can contact life on Uranus.

Way to call it Fatsqatch, but maybe Charles K being a rookie driver just had unrealistic expectations on what was mechanically possible for any truck to make the grade with a heavy load. :/

Ya know, sometimes you might find you don't get what you need, and you will find it better to back off, and return to behind ol' pokey because you just don't have the power to speed up this time.

You might feel embarrassed, but others being you, including 4 wheelers, could say "Now there's a trucker who has some sense. He's backing off so the rest of us can get by."

(Note to Fatsquatch: if you had used the term "p*ssing contest", no one would be sure if the missing letter is an "a" or an "i".)
