Gday...

Certainly a nifty idea - simple to use, light to carry, and quite practical.

My only concern would be what if you drove forward just that LITTLE bit too far - and the whole shebang fell back to earth from the maximum height ... or if when finished you forgot to reverse to lower the trailer/vehicle, and drove forward, and it came down with a thud.

I know conventional jacks - scissor and/or bottle - can topple over if not used correctly/safely/properly .... I wonder just how stable this one would be if used away from a nice smooth, level concrete pad as shown in the demo

Will not work on my Aliner ,but a good idea anyway.

Note they dont show a deflated tyre, I'll stick with the trailer mate.
