The SUV/Cargo topper ships flat which means the top panel and sides are independent parts. I doubt there will be an alternative roof for the cab, but an alternative roof (top panel) for the topper could be interesting. Why not have an option that is partially fabric and folds back? While you’re at it, why not make it a tent that you can climb into from the bed…kind of like what Alu-Cab developed for the Toyota Troopy.
