Hull Trailers, would purchase the 16' offering. http://hulltrailers.com/index.php?option=com_content&view=article&id=19&Itemid=26 Any thoughts? It would be used for mowing. All it would EVER haul is two ZTRs, and maybe a WB. I like the design, just not 100% sold on the solid sides which appear to double as a structural component. I have no experience with these solid sided trailers vs standard angle iron.
