Feedback from costume designers and supervisors alerted Waggoner to two small upgrades that made big differences in efficiency. “We found out that a closet to store the steamer needed a plug. So we added it,” he said. The company also installed a hook near the trailer’s office to ease the flow of wardrobe items and paperwork.

Costume Designers have other suggestions, too. Ivy Thaide, Assistant Costume Designer on “Pretty Little Liars,” would love to see more electrical outlets in the walls among the hanging racks, along with pull-out mirrors, strong WiFi, cabinets tall enough for multiple steamers and, very important, window tints or shades that block the glass doors.

Christopher Lawrence, Costume Designer for “Ray Donovan,” has a wish list that includes strong WiFi capabilities. “That’s number one these days,” he said. He also appreciates the jockey boxes beneath the carriage that have pullout drawers.

“I absolutely prefer a top-loading washer,” he said, joining a chorus of other designers who prefer them to add pieces mid-load or use the tubs for dyeing.

Gradually, their needs are being met as operators upgrade and replace trailers.

At Rag Van Rentals, founder Edward Marks increased the number of electrical outlets to service phones, printers and more power-hungry equipment. His newest van features Caesarstone countertops and high-end audio-visual equipment.

Keith Fisher, of Transportation Resources, has made trailers winter ready with powerful heaters, insulation and climate control. “You can bring it to Toronto in the winter and still do laundry,” he said.

When your cubicle is a narrow, rolling office, workshop and storage facility, sometimes, it’s the little things that count.
