The shop called me just before lunch to say the work was done and ready to be picked up. I shot up there over lunch and picked it up. The shop techs, re-curved the springs, re positioned the axle above the spring, and aligned them. Now it sits as an Airstream should.
The ride back to the house was uneventful and no sway or nasty noises from the rear. This without shocks, as I did not give them to the tech.
Overall, new axle, hubs, breaks, re-curved spring, added capacity to the spring, heavy duty shackle and U-bolts, bump stops, and replaced all the grease bolts for under $1000.
Here's a picture of how it sits finished.
