We have done it in our 36' Dolphin the opposite way from Grants Pass down to Crescent city but end of next week we will do it the way you are describing. No it is not as much fun in the motorhome as on my motorcycle or in my little BMW but it is very do able without remodeling the seats with crinkle marks from tightening sphincters! :B
BTW we don't have the time on the way up but if you do I would continue up 101, we will come home that way the end of June. Need to get up to Portland after I do some work in Livermore next week for the birth of our first grandchild due May 20! :B :B
