"I agree that looks like a good place to lift it, but how about off center somewhere if I only wanted to do one wheel at a time?"
I'd still jack at the draw bar bracket...
Even when I've only had to pull one wheel, I've used the process described. That's a solid axle under there. Personally, I think jacking one side may stress the axle...especially where it attaches to the differential. As far as any real potential for damage...I've no idea, but I know jacking at the drawbar bracket won't hurt anything.
