We're hoping to head out to the Deschutes and Willamette National Forest(s) by way of Sisters, OR.....leaving on May 8th for a few days. Will be taking our Sportsmobile (Sprinter 4x4). Anyone have suggestions on some good offgrid camping destinations in these forests? Not looking for any technical offroad adventure (that's what our FJ is for) but bumps in the road are fine. Thanks.
