I am taking a trip pulling a trailer to Bend, OR. I will be taking Hwy 97 off of I5. Does anyone know what the terrain is like? Does the route have steep climbs like I5 through the Siskiyous? From google maps, it seems pretty mild but that can be deceiving. I think there is a pass that is higher. I don't care about that as much as how steep the climb is. That's the part that causes the overheating.
I have taken the train north before and from what I can remember, it takes a similar route.
