I have a 1999 4-runner with 3124ks and constantly go up I-70 with it. The steep grades will definately slow you down. 7% grade will slow you down to 30-35mph with a 6 cyl. This includes wolf creek pass in southern Colorado and on 1-70.
The things to remember on a 4-runner is to take the overdrive off and leave it off. Make sure you have a sufficient transmission cooler. The coolers with the built in tow package is sufficient---"Part of the radiator".
If not, it should be a heavy duty one...
Make sure you have a good brake controller.. eg. protegy, because the brakes will get hot very quickly. 4-runners have thinner rotors. Use your engine braking often.
You will also need an equalizer hitch. I have the equalizer brand 1000 lb. and it works very well on the 4-runner.. If you don't, your headlights will be in the trees.
The SUV works very well towing a 3124ks on normal freeways that are 4% incline or less.
