The osgSim::DOFTransform node is a specialist node used to support OpenFlight databases, it's not used by any other loaders, so a .3ds model won't have any DOFTransform nodes in them, so you certainly won't be able to use dyanmic_cast<> to magically transform nodes loaded from anything other than an OpenFlight database, even then you'll need to go a search the loaded scene graph, using a custom NodeVisitor, for the DOFTransform nodes. What you most likely require is to simply decorate your loaded scene graph with a osg::MatrixTransform or osg::PositionAttitudeTransform node to place it where you want. See the osganimation example for an illustrtation of this.
