Any advice for road-tripping around Vancouver Island, British Columbia, Canada?

I would like to take a roadtrip at the end of July up and down Vancouver Island. Has anyone done this before, and if so, would you recommend doing it? The plan is to start in Nanaimo (take the ferry from Vancouver), then drive north to Port Hardy, go hiking at Cape Scott Provincial Park, then make our way down to Tofino, and then back to Nanaimo. We’d like to camp and hike as much as possible. Would this be a good trip, and does anyone have any recommendations on where to go/stay? I’ve already googled this, and there are not many resources, nor are there many guidebooks on this region. Thanks.
