Joel -
If I understand you correctly, what you are doing is jacking up the tongue and then pushing it off the jack. I have done that in order to move a car under unfortunate circumstances, and it is an interesting process, to say the least. As long as you don't jack it too high, I concluded that it is not too dangerous, and as you point out, the high-lift jack doesn't bend or break because of the pivot on the foot. However, when the tongue comes off the jack, and is moving sideways and down, does all the moving mass come down on the tongue jack's stem? Again, as long as you keep it near the ground, the jack stem is probably strong enough to withstand that sideways force. But would it make sense to have the wheel on the jack, so that as it comes down it can roll in the direction you want it to go?
Or am I misunderstanding your technique?
Bill
