I was stationed temporarily in the air guard in Southern California, they flew the 130, while there I saw their fighting the wild fires around Los Angeles, below are some images I took and others fron the photo lab dup 35mm slides, where the sky is orange that is smoke from the wild fires at sunset.
I've seen them operated as tankers several times around here. There some over at the tanker base here in Fresno last year. It would seem that as each fire season becomes worse, we will see more of these operations.
