It has come a long way, but it's ready to use again.

.

I still plan to do something with the chain, and I'll probably cut off the side jack eventually. It could also do with a storage box in front. I haven't decided if I'll build removable ramps or a hinged gate/ramp...
The new
tongue jack was ~$70 at TSC, and seems to be very functional.
It has 4 new ST225/75R15 Transporter 10-ply tires. ~$350 in Aug.2019
