The pic you posted is the only one I've seen. Certainly looks different, but if the footprint is big enough..it should be stable?
I just checked it out on Redline's website.
Under the shipping tab they say it cannot be delivered via liftgate to a residential address.
The shipping crate is not pallet jackable.
Here in Sweden there is no delivery restrictions on them, and this on (in the video) is a bit less $$. About 3700. I can't use a 4 post, even if it's mobile.
In the video the guys says it will flex a bit, thats normal, and he recommends the tall jackstands if you are under it.
Just investigating this, setting up a new shop this year, would be nice with a lift.
