Looks like the ride height valve is broken.

And the underside of the landy is dirty too. Tut tut....
I agree with your assessment weeds.
Years ago after I rebuilt the 110, and it was in at the mechanic for the last big push and roadworthy. A week or two after I picked it up, the rear wheel fell of just like your camper. I’m guessing the RW guy took the rear wheel off to look at the brakes and forgot to tighten up the wheel nuts.
Anyhow, none of the wheel studs broke. I took a wheel nut from each of the other wheels and refitted the wayward wheel with 3 wheel nuts for the trip Hm
Maybe look st upgrading the wheel studs.
Does John like broken bits? [bighmmm]
