Hi Yoda,
I have just posted the following info on the caravanersforum web site.
It is in the Technical Forum area.

Hello new JEEP Grand Cherokee Owners
If you are towing your caravan with a new WK2 JEEP Grand Cherokee 3litre Diesel and you want a snorkel for it then please add your name to the list at Airflow Snorkels. The demand is growing and is currently at about 50 BUT 150 serious enquires are needed before it can become a reality. Please feel free to enquire directly to airflow via email;
info@airflowvector.com or via their web site or facebook.
Cheers,
Peter
