There is a bracket for AL-KO trailers that Cobra uses. This is for a caravan. Should work.https://www.youtube.com/watch?v=bux1kg7wxCg

Interesting! Looks sturdy but I guess one would need a special jack which 'slots' into the bottom of that bracket. I wonder if a standard jack could be used on the upper horizontal part of the bracket.
I will check the frame on my Cobra trailer this weekend.
