The Airstream marked jack point
should never EVER be used.
I have been on Airstreams case for over 3 decades to "QUIT" installing that marker.
WHY you might ask?
1. You cannot see the frame, therefore you most likely will not center the jack.
2. You must get under the trailer to assure that the jack is placed "dead center" of the label.
3. Should the jack not be centered, as the trailer lifts, the trailer becomes somewhat tilted.
4. When thast happens, the jack can easily slip off.
5. The frame will be bent if the jack slips inward.
6. A hole will be punched in the underbelly.
7. A hole may be punched through the floor as well.
8. If the jack does not slip
you will at least damage the underbelly appearance.
Now lets see the disadvantage of placing the jack on the axle mounting plate, between the wheels on a tandem, or behing the wheel on a single axle trailer..
1. You should get under the trailer to make sure the jack will indeed lift the trailer from the axle mounting plate.
Sorry, can't think of any more.
There is way too much "guess work" using the Airstream lift point.
None at all using the axle mounting plate.
