To my knowledge, Maya does not have an extrude method that works like what you are seeing in Modo and even 3dsmax. Hopefully one day though it will as it would be very helpful especially for complex objects that are not symetrical in anyway. I like to use the method that stwert mentioned. I've never run into any geometry that it wouldn't work on, you just have to merge verts afterwards. It takes time but gives perfect results.
