When we first got our trailer we were practicing in a parking lot and it worked fine.
Got it home and figured let's try backing it in with it and see how it does. Nope wouldn't work once on the rough/ grass/ dirt.
Trailer was pretty level.
Since then we have never used it again. Haven't needed too.
Our friend said he has had the same issue.
Once on a hard packed surface seems to work.
Sorry no advice on how to make it work, been over two years and never needed it.
