That rack looks heavy, how much do you think it weighs? I'm assuming it's for a stage. Also supper curious to how it drives

I don't think it looks too heavy, not more than, say, the bus's original seats. And with so little wind resistance, I wouldn't expect it to affect handling too much, either.

This album has been a great inspiration. I don't know if the original author is around anymore, but thank you nonetheless.
