-> take highway 2 into Everett/Seattle. It's the most beautiful thing you'll see! Seattle, WA (spend more time here - see Pike Place, the public library, which is a beautiful, tall and extremely modern building downtown)

Olympic Peninsula (skip this - stay in Seattle longer)

Portland, OR (Seattle is way better - but if you're in there, go to Saburo's - http://www.saburos.com/ - you might have to wait an hour, but the sushi there is incredible.)

Driving down PCH is a great plan. I like the northern better.

I saw a bunch of other stuff, but Oregon's not nearly as impressive as Washington or Northern California (don't miss the Bay Area, of course, but don't bother driving any further south.)

We went from LA to Vegas, and it's skip-able. Utah was OK, and from there we went to Denver and then back home.

The whole trip was over 7,000 miles.

Anyway, focus on the pacific northwest. It's just beautiful. I was just in San Diego for a week last fall, and it's awful. You'll just wish you were in SF, so stay away from San Diego.

And if you're into Canada, try visiting Banff. I'm going there next (on a trip that will take me to Alaska and then to Hawaii by ferry.)

You're probably going to hate your truck. I would get something sleeker.
