While not a common combination of products it is possible to attach a pod to a platform. The ease and required parts will depend on the brand or model of platform you have. Platforms with the planks running East-West across the vehicle will typically allow the pod to connect straight to the plank. Platforms with planks running North-South along the vehicle will require an attachment bar before any pod can be considered to be mounted.
The type of pod able to be mounted also needs to be considered, only pods with quite flat bases will usually attach to platforms as any indents can prevent the mounting hardware from making contact with the platform. The Cruz Easy 320A is an ideal pod for mounting to a platform for these reasons.
