I've just been through Rainbow Road on a guided tour, and definitely wouldn't recommend it in a 2WD campervan. It's not officially open yet, but should be open by December 1. Best to check first, though. Toll is $40 for a 4-wheel vehicle.
It's a few years since I went through Danseys Pass, but at that time there was nothing that should discourage a campervan from going through. I'd stay off Hakataramea Valley Rd in a 2WD campervan, though.
