Do you push or pull it along? Are the wheels these, we don't have a Northern in our area but I can order online. These are pretty inexpensive. Who doesn't have a suitcase like yours laying around? I have a Calumet C1 8x10 sitting in one right now. There wasn't a good inexpensive case for it so I just put it in a suitcase to store it. Add some wheels, an axle, a handle and it's good to go. Did you attach the axle to the case with some metal brackets?
