Thank you guys,
I was suspecting something like that (foolproofness).
There is this cool alu carrier (

and I was hoping there is a 2" receiver for vibe,
but I guess there isn't.
If I get it - will it be ok to put a big cooler on it and fill it up?
Simple math: classII gets upto 200lbs, right?
the carrier itself is about 30 lbs so it leaves about 170 lbs.
Considering there will be an adapter (1 1/4 to 2 inch) it will
act as an additional lever. Do you think it will still be ok?
