Try to make Baker 17 miles long grade at common 120F and if you pass, you are good to go anywhere.

Yep ... how right you are!

If your truck can't move it's whatever load up long haul grades in August in the U.S. West with your cab air on full blast and engine temp needle not budging ... then you need something better.

So far after 15 years of ownership, the V10 E450 pulling our 12K lb. MH all over the West in any month hasn't even blinked. HOWEVER - I haven't tried Old Priest Grade with it, yet. :B
