Looking for collapsible crate for large dog

We currently drive an SUV and travel with our large metal crate when we take our 60 lb Aussie mix on trips. The problem is that the crate is so large, we have to fold down one of the seats to make it fit, which leaves little room for luggage, other passengers, etc. Can anyone recommend a secure crate with at least some wire reinforcement that can be folded up? The typical black wire crates that just fold into a large rectangle won’t work because that’s what we have now.
