How am I going to re-attach this jack?

It’s not the end of the world. You’ll get it fixed. No camper hasn’t goofed.

Photo here of the jack on a '99 Fleetwood Elkhorn 9.5. There is some split lumber in there. Thanks!

post your image here.

Image did not come through. We'll need more info too, like make & age of camper. Many here have dealt with what your going through.
