As the Hyundai Ioniq electric is only allowed to be fitted with a trailer hitch with a cage, the Hyundai dealer fitted me with the official Hyundai trailer hitch from MVG, the one with the "cage". Question 1: Does the Atera Strada Sport M3 fit on the MVG towbar with the "cage"? Among MVG's recommendations, the Atera Strada SportM2 and Vario2 are recommended. Question 2: Are the Atera Strada Sport M2 and M3 identical in terms of attachment to the trailer hitch? Thank you.
