I don't think you have enough time to get all the way to Vancouver. That would be a lot of time driving with a lot of people plus a dog for that truck. Remember, every time you break camp and move, you lose an hour or more time that it takes to set up and tear down. Find a series of campsites and spend a couple of days at each. My ideas:
Stop and see your parents. From Redding, head to Lassen Volcanic NP. Hike to the top. Hike to Bumpass Hell - kind of like a miniature Yellowstone experience.
From Lassen head north to Lava Beds NM. Take some LED headlamps and explore the lava tubes there.
Map of caves with descriptions With few exceptions, you are on your own to explore all these caves.
Then it's on to Crater Lake NP. Take the boat tour. Drive around the lake.
Off toward Bend. Camp at
Newberry Crater. There are NFS CG's right in the bottom of the crater by the lakes. Sort of like camping at the bottom of Crater Lake. There's a lava flow composed of obsidian right off the road. In this area, there are lava tubes to explore. Lava Lands visitors center south of Bend has some interesting landscapes to explore. Like to mountain bike? Some fun trails out on the Cascade Lakes Scenic Byway. Check out
these options. We've never done it, but rafting on the Deschutes is supposed to be quite good.
From Bend head north to the Columbia River Gorge. Some great hiking trails to numerous waterfalls on the south side of the river. If you really are adventurers, hike/wade up
Oneonta Gorge and Falls. Check out the Bonneville Fish Hatchery and dam/locks.
Lots of opportunities here.
By this point, you are at least half way into your trip. If you really want to push it, head a little further north and explore Mt. St. Helens. Pretty awesome display of the power of nature.
But it's time to head back south. Go over to the Oregon Coast and work your way back on US 101. So much to see and do along the OR coast. Last time we went, we spent over two weeks playing just on the southern half of the OR coast. Grab some kites and play at Cannon Beach. Explore some of the
lighthouses. Get a copy of the tide tables and explore the
tidepools at low tide. Stop at the Tillamook Cheese Factory and get some ice cream. Sea Lions Caves. Oregon Dunes. Sea kayaking. Sunset Bay SP has a great bay to play in as the tides go in and out. Beachside SP is, as the name implies, right on the beach. Right down the road is Tillicum Beach NFS CG. Also right on the beach. US 101 isn't a speedway, so it takes some time to work your way down the coast. But you'll be stopping often to take pictures anyway (that's why I've routed this loop heading south along the coast - easier to get in and out of the scenic overlooks).
As you near California, consider camping at Harris Beach SP and exploring the northern CA redwoods from that excellent CG. Check out the
Ossagon Trail for an amazing mountain bike experience. Yes, some road work too, but the ride through the redwoods and then down the coast is amazing.
By this point, you will have a few days left to get home. An overnight in Humboldt Redwoods SP gets you camping right among the huge trees.
I hope you follow the links I've given you. Each one lists many opportunities for adventure. For the loop I've given, Allison and I would typically budget six weeks, so you'll have to pick and choose. Can you go further, sure. But you're sacrificing outdoor activities for time staring at a windshield. Make this a fun trip and you'll eke out a few more years of camping with the kids. Make it a slog to see how far you can go and you might not get them too excited to go again.
