Hwy 20 Sisters to Lebanon for a 40' motorhome towing.

I believe it's a 55' restriction on that stretch of road, west of where 22 merges. I don't think it would be very fun with a large motor home, but it's doable.

We took US20 from Burns to Newport last summer. From Sisters to Lebanon it is fairly twisty and steep. And a very pretty drive. Certainly doable but kind of slow. Between that section and the construction around Eddyville and since I prefer to take different routes, I decided it wasn't worth it on the way back and took Oregon 22 past the lake. This is way is easier and also scenic.

There are lots of twists and turns and ups and downs. We have done it about 10 times in a 38' Gasser and a 41' DP towing all the time. It's a little work but a nice ride. I'm always looking for Sasquatch to cross in front of us.

Trip check shows no restrictions. Some construction with minor delays.

242 out of Sister is not an option as it's limited to 35'.

Last I knew, there were weight & length restrictions on that road because of road slippage & repair. I would check with the DOT before taking that route through Sweet Bome to Lebanon. The road through Stayton past Detroit Lake is a much better road and won't add many miles. Enjoy the drive!

US 20 is a good two lane highway. Be aware that many trucks use it.
Great scenery!

Yes, Sisters, Oregon and Lebanon, Oregon.

Sisters in Oregon? Or?
