I liked the ideal of a 2 ton jack, a bit of margin over 1 ton or 1 1/2... but it doesn't fit the cutout in the foam. Just in case anyone else was considering it.
So through the miracle of Kijiji, I’ve ended up with a genuine Toyota tool set and jack out of a Corolla… rated at 1000kg. Think the ‘recommended’ Prius toyota jack is rated at 1100kg… so I’m trying to reassure myself it’ll be adequate.
