There’s this, minus the Honda branding and zippered access to the trunk it’s the same thing: https://www.amazon.com/Napier-Outdoor-Sportz-Truck-Tent/dp/B00VB3W8YG/ref=sr_1_1?dchild=1&keywords=napier+compact&qid=1621578970&sr=8-1
But if you’re a cheapskate like me and you’re feeling lucky, there’s this option: https://www.ridgelineownersclub.com/threads/ridgeline-oem-truck-bed-tent-available-anywhere.227047/
I ordered one for $40 shipped, figured I can’t lose even if I only use it a couple of times (I have lots of tents). It’s in a box in the garage, haven’t had a chance to open it up.
