2 of my favorite things, Subaru’s and trucks. I can vouch that this works, as when i had my Subaru I used it for the very same job. I pulled my truck (only a 7.5 tonner) out of the mud. They obviously provide just enough traction and pull to help said stranded vehicles out of their predicament!! This is a good example, the poor MAN is stuck at a slight raise in the road at the level crossing and the Subaru gives just enough to get it up and over…….. i just hope the truck managed to stop on the other side!
