Yeah I was thinking of the magnetic lights for my Axis as well.
I think I came across a hard plastic cargo box that was large enough for two bikes. But it was expensive (like $800 - $1000??). Looked nice. I think it slide into the receiver hitch as well. But it might be worth it in the long run.
Do some searches on Amazon.
