Joann,
I think that what precludes you having a wheel installed on the jack is that
the tube pulls up way too far into the outside jack pipe/tube. Also,
anything hanging below the plane of the bottom of the jack tube would surely
get destroyed the first time the rig bent in the middle going from a
driveway to the street, etc.
Now, IF you could re-mount the jack high enough .... no, don't do that! ;)
