I would not think so, the Protoloads have the dunnage attached already, BUT, I know little about how these are loaded in real life, other than seeing pictures.d with the "Tyco" like appearance of the BLMA loads, which do not come with lumber between each level. The protoloads are aluminum tubing, which also gives the car weight. Wish they would do some of their other HO loads in N!
