canopy tailgate cap

Condition Used - like new Selling my Alu-Cab Contour Canopy / truck cap for a Jeep Gladiator JT. This is the high-end aluminum Alu-Cab canopy, not a basic fiberglass camper shell. It is strong, lightweight, lockable, weather-resistant, and works very well for overlanding, camping, work gear...

The standard tailgate cap is like a spoiler, well here in Australia it seems to be the only option. This does not sit well with the Camp King Canopy Campers rear door seal. Are there other versions available?
