Our truck is currently being used by Australian friends with whom we have done a camper swap. They managed to lock both sets of keys in the cab. Anyone have directions on how to use a Slim Jim on those door locks? They've called road service but I thought if anyone has experience opening those doors with a Slim Jim it might be helpful in resolving the problem. I do own a Slim Jim and they are relatively close to me so in a pinch I could go there and attempt it myself but I'm not an experienced jimmier.
