No Problem with that route. After all your hinged in the middle
I take it every year from Shasta Lake to Medford where I get gas at Fred Meyer or Costco then up to Hwy 227 at Trail, to Canyonville and the Seven Feathers RV Park, top off the tank then head to Dillard / Winston, Hwy 42 to Myrtle Point to Coquille, Hwy 42 S then to Bandon.
BTW there is a scale south of Bandon a few miles on the left that you can weigh your rig on for free. Also the 76 gas station south of town usually has the lowest price.
