not a krusty even worse after ww2 people were conecting to gether weasels i would bet thats what it is kind of looks like a weasel with an air stream trailer attached.it couldn't be.....a...a.... fullcab Krusty KT4 pulling some sort of cargo sleigh(full of spare parts of course to keep it running) but even that wasn't enough to keep it running so they had to call in a rescue party consisting of both chopper and plane. Yep...gotta be a Krusty KT4! Notice The operator and passengers walking around trying to flag down that plane so they can get rescued.
