With today's ever growing special event deployments requiring larger quantities of equipment, Sun West Engineering has come to the rescue with the Remote Radio Head Trailer.  This trailer has the ability to carry up to 40 installed and plumbed remote radio heads. All RRUs are installed on full-extension ball-bearing steel slide-outs, allowing for ease of installation/maintenance and additional cooling when necessary.  The RRUs are permanently plumbed to a rear mounted bulkhead port panel so the equipment can be pulled up along side another COW (like the scissor lift COW), and connect directly to the antennas or another bulkhead port panel.
