Jack with wheel attached...
Here are some pictures of the wheel on the jack....
Note that I not only drilled the bottom of the jack post to accept the stub of the wheel assembly, I also cross drilled a hole and use a quick release pin to hold them on the jack.
Sorry for the fuzzy pictures... still clear enough to get the idea..
One note of warning... My camper is pretty light (<1000 lbs) so I don't have issues moving the camper with the jacks fully extended, but for safety, I drop the camper down to its lowest point for storage and moving it around the shop...
Use at your own risk, I don't want anyone coming back on me beacuse they dropped/tipped their camper or had it roll out into the street!
