Crate for Roadtrip

Hi all, I’m picking up my golden retriever puppy in a couple of weeks and am in need of a crate for the road trip. It’s going to be a 12 hr drive, he will be 9 weeks old.

I have a mid size SUV, Mazda CX-5 and am nervous to have his crate in the trunk, god forbid there’s an accident.

Anyone have any crates they recommend that can be bucked into the back passenger seat? I’m not looking for mesh or those open car seats that I keep seeing online. I’m looking for a hard plastic crate, but would love recs.

Thanks!
