Given the GTM and ball weight issues one of the swaggers had with his new T-Van, I don't think it would work behind a Jimmny.
Indeed ball weight can be an issue.
Ball weight on an Ulti (unladen) is 35kg...
People towing Ulti's with Subaru's, VW passat, and other lighter vehicles...
No doubt, there's probably other light weight camper traier option as well...
