Towing through Eisenhower Tunnel
Just wondering if anyone has towed over the Straight Creek Pass through the Eisenhower Tunnel on I-70. I will be going there this coming week. The pull going up the east side is about 12 miles of 5%...

We pulled up that west side hill in June towing about 12K lbs with a 2005 Duramax 2500. Truck did fine... tranny and engine got hotter than usual, but still withing specs per the owners manual. At the top of hill we were doing about 38 mph. Went through the tunnel and down the hill at that same speed without issue as far as downhill speed, with only a few taps on the brake. What was bad was the ruts/grooves on the downhill side from the semi's.
