Ford Ranger 2018 Canopy Dog Guard

Hi.

Has anyone got examples or ideas on the best way to separate the rear bed/canopy so that I can have my dog in one side and storage on the other? Basically a central divider that goes the full length of the bed instead of the width of it? Has anyone got examples of mounting a central divider in a ranger and how they've achieved it?

I know theres lots of custom built cages and custom built storage concepts but i'm looking for something a lot simpler and cost effective.

I've got a Great Dane and putting him in the double cab with the family isn't practical so we want to ensure he's safe and secure in the bed/canopy for when we travel, go camping etc without the worry of stuff we travel with invading his space.

Thanks
