Those carriers that offer 28' trailers might be a partial solution. They tend to be less expensive and hold a maximum of 26 gaylords (more likely 24) double stacked, or 13 single stacked gaylords/pallets. Inexpensive but heavy items like UPS's can make up a lot of weight, as can towers, switches and servers (presumably if they're not new enough to harvest parts nor old enough to be scrap gold mines).
