US 30 West from Longview to Astoria OR

We made that route in July coming off the Longview bridge going to Astoria, we just had our tranny beef up with a shaft kit, deep pan cooler and a three stage converter and wanted to see how it pulled hills, that was the only hill around the Portland/Vancouver area that would give it a good test, our 7.3 Ford pulling a 15,000 40fter 5er did better then I thought, maintained 45mph, but that torbo was howling!! and the one post was right, you can't get a run at it off that bridge. The other hills seem alot easier coming back from Astoria. Next test was going down that 7% grade to see if second gear would hold back that much weight, held it at 50 with a couple brake applications.
I know this doesn't have anything to do with the first post question, just had to say........next is Cabbage Patch Hill out of Pendleton Or.
