Here are the ones that came on my TT - http://domarproducts.com/stabilizerjack.html
One seems to be rusted at the pins, can't really tell at the screw. the other, has some rust but not much and I'm not exactly sure why it's not working. The one I replaced earlier, the piece where you attach tool snapped right off the screw.
Also, forgot to mention, my manual jack tool broke too. the pin that holds the socket piece on snapped and the socket fell off.
For now, I may just get a replacement via warranty (I'll call local dealer).
I see bal makes some pretty much identical to these.
The other type that would work is this one - https://www.etrailer.com/Camper-Jack/etrailer/TJ01RT-HD.html?feed=npn&gclid=EAIaIQobChMIrK22xpCG3wIVnv_jBx0A1gvIEAQYASABEgIa9_D_BwE
However, I'm not too keen on having it being manual jack, prefer something at least drill operated.
my TT and the stabilizers are made in indiana, maybe that's where the rust came from.
