Looks like a wavy Mopar axle.

 

Yep, wavy Mopar tube axle...with the original Mopar lug BOLTS! (left hand thread on left, R.H. on right)
Young techs at tire stores don't know this, will break 3 on left side removing wheels before they 'snap' to the fact there are left hand threads on the left...
Looks like a Mopar wheel, too. (no inner or outer 'nubs' for hub caps)

 

I see why they call it wavy. It looked factory but I wasn't so sure it didn't get modified by a tree stump. Thanks guys!

 

Does it have bicycle wheel bearings or tapered rollers? I had an old tear drop trailer made out of one of those back in the mid 70's. Worked great!

 

i see 3 outer hubcap nubs... in the pic

 

I am in the process of removing it from the homey built trailer its under
