Thanks for the response. I guess I wasn't very clear in my original post. I know Bend is not on I-5. That's the reason I'm asking about Hwy 26 & Hwy 97. Hwy 26 runs east from Portland. I'll be coming south, from Washington on I-5. My intention is to take Hwy 26 East out of Portland to Hwy 97. Then Hwy 97 south into Bend. I am concerned about pavement conditions, sharp turns and low overpasses. Since this is a major truck route I shouldn't have to worry about those concerns. The only obstacle left would be weather and weather related road conditions.
Again, thank you for the response. This is my first post on the Good Sam forum. I'll try to be more specific from now on.
