As long as the flat deck is at least 48" x 84" you can set up the Rev Rack Tent on the platform. Choose the "other" mounting system when purchasing.
You can transport the Rev Tent on smaller K9 racks. For sleeping on the vehicle roof with a smaller K9 Roof Rack you must purchase the Rev Roof Top Tent because it includes a platform that mounts to the K9 rack just like any traditional Roof Top Tent.
