The RocketBox pro is made with cars in mind. And it does hold a decent amount at 11 cubic feet. Because of the shape, you can also fit skiis/snowboards in here if that’s your thing.
They offer a limited lifetime warranty. This is good until sold. If you pick one of these up second hand, it won’t apply.
This is a side opening unit, but it can open on either. Locks are included with this as well. We really like this unit all around, and if you’re looking for a long-term option for your Nissan Sentra, this is worth a second look.
