Thanks for all the suggestions. We'll plan to avoid Seattle during rush hours and will take the suggestion of WA 18. Nine years ago we traveled from north of Seattle to Yakima (thru Seattle early on a Sunday morning) and my cousin gave us directions (long lost) for a way to Yakima that gave us a beautiful drive. While our rig was being worked on in the factory we explored some of the wine county and had a great day.
That beautiful drive would likely be what I know as the "Valley Highway" which is the old highway (WA 821 exit 109)that I82 replaced. I runs south of Ellinsburg to Yakima I runs along the river and is a bit twisty, compared to the hilly I82.
ON EDIT: PS: If you are not in a hurry, and want to enjoy the view more than make time, after going to Yakima, take Highway 12 west from Yakima over White Pass. Then at Morton (West side of the pass) turn north on Highway 7 to Elbe, WA. From Elbe you can head east on HY 706 to the main entrance to Mt. Rainer. There is a nice RV park just outside the park on the south side of the road.
Once done at Mt. Rainer you can continue north on HY 7, it will bring you in on the backside of JBLM, skipping Seattle and Tacoma!!!
