Grants Pass, Oregon

Heading over Grants Pass north bound. Any issues with a 1 ton diesel pulling an 11K 5th wheel? Fairly hot out here in N. California, close to 100.

There's one section at the south end of GP. Long uphill climb. Extra lane for truckers. If everything's in order with your truck you will be fine. It's nasty if you are merging on the freeway at the bottom. Takes awhile to get up to speed. If you make it thru the Siskiyou's you'll be fine.

Keep the trans in 3rd/4th and steady pressure on throttle. Engine rpms around 2200 or so and you'll be fine. Just did this on Mon this week. Then thru WA to MT where we are today. Don't try to maintain a set speed, just rpms and let the engine find where it's happy. Keep an eye on temps and stop if you must.

If we can make it through with a 4.8L Chevy Crew cab towing a trailer and we were carrying more weight with us than usual, than you should be good. We just made this trip a few nights ago, we were traveling late afternoon and evening hours to avoid heat in the day. We only stopped at rest areas to stretch our legs or grab something to eat, never did have an issue with overheating

Although we may take an alternative route to drive home such as the 101. The hardest climb is the Siskiyou Mountains and before that is Ashland. I've just found out on this forum, another member took the 97, which avoids the uphill climb, but a longer route. Unless your carrying more than your usual weight in your truck/trailer combo it might pose a problem. Here is what he mentioned:

There is a climb out of biggs junction to the top of the hill. Stop near Madris and stand in the middle of a large circle of rocks, each aligning with a major mountain, I think there are seven. There is the very deep canyon north of Bend. A lot to see, we love the back roads, you miss so much on the freeways. ENJOY
