Hi....Going East(June) on I-70 from Utah. How bad are the grades at the Eisenhower Tunnel and Genesee Hill. Would it be best to unhook the tow car at these passes.What do you think. Thanks. lenOrge

If your rig is in good shape you should have no trouble.

I've handled those grades in a 33' Suncruiser/Workhorse W20 and with a 40' Allegro Bus and had no problems. There are some long grades anbd you won't set any speed records but there are truck lanes at the tough parts and you won't be in anyone's way. Just be sure your cooling system is well maintained before you leave. You won't have to unhook the toad. The only two times I did that (4,660 lb Grand Cherokee) with my Suncruiser was when climbing the north face switchbacks on the Beartooth highway and when climbing the Bighorn Mountains via US-14A because those were extremes.

Len,
We just came through there a couple of weeks ago (we were in Breckenridge for Spring Break). You will find the steepest (up) grade from Dillon to the tunnel, it is pretty much downhill from the tunnel to Denver (6-7%). We kept our toad (~4,000 lbs.) attached without any problems. Uphill we just got in the truck/hill lane and put the hazards on, slow and steady.

We did about 25-30 MPH uphill on the steepest grades and downshifted to keep the downhill speed to 45-50 MPH.

Have a safe trip!!

Cheers!

To me the grades at the west end of I70 in Utah are greater that at the tunnel in Colorado.

I have done I-70 all across from Denver to end a few times in my old 11,000 pound 1990 Fleetwood with 454 engine and towing my 3200 pound Honda with no problems at all. Its more fun in my current Dutch Star Diesel but you can do it OK.

Utah part is very tame. Nice rolling mountains and beautiful scenery. I like to stay in Green River and leave in early morning and its a fantastic feast for the eyes.
