The DND has special purpose built sleds for behind snow machines. When up North, however, the Inuit's qamutiik are much longer so have a greater cargo capacity over the DND ones.
There is mention that the nose of the diesel machines are quite heavy. As such, they are more likely to get stuck in softer snow. My limited arctic experience was that the snow in the arctic is not the same snow we have in the South. The ground ranges from very thin cover of snow with rocks peeking out, and where there are drifts, they are generally quite hard packed.
