The photos I have show the barrel trailers to be of distinctively different construction than the rest. (The photos I have are mostly post fire). They appear to be stake bodies. Looks like they built wood frame walls and roof around the barrel. And I can see the fencing material in one of the photos. Thanks! I'd post the photos, but I had to sign a copyright with NFPA.

I am presenting a recreation of the fire at the NFPA national conference in June (2014) and have some questions that someone here may have answers to. Here's a few: Does anyone know how the fiberglass barrel worked? Did you walk across the barrel as it spun or was there some type of bridge? Also, the adjacent trailer had vision panels cut in it which overlooked the barrel. Were these plexi-glass? The barrels were on flatbed trailers mounted on wheels to make the barrel turn, was there a weather covering beyond the barrel? Thanks.
