Off Road Trailer Information

Tradesman Toppers for HD Trailers

We saw these semi-custom Tradesman Toppers at Overland Expo last May, what do you think about this option for heavy-duty Off Road Trailers?
The Access Manfuacturing Website doesn't have any information on these toppers, but they seem like a good idea for many wishing to expand the use of their trailer. Perhaps with enough interest they could mass-produce a setup like we see here.
