who makes a 20ft 8lug car hauler?

I have a 18ft 7K car hauler, and alot of times its not big enough for what I want to haul. looking to move up to a 20ft one, with 8lug axles under it. can't seem to find one on the websites i've been checking, I guess maybe I need to call them to price one, but was hoping someone on here might have some good leads or links.

whatcha got? thanks.
