Thanks John for your interesting perspectives.
Not a lot of front-and-back-loading cargo haulers like the Argosy any more.
If you like old British types, some Bristol freighters did the rounds of Canada's north, and one is proudly still on display in Yellowknife if you care to visit.
Just the other day I had a surprise chance to walk through and take pictures of a Shorts C-23C Sherpa, formerly of the US Army. What a perfect vehicle for hauling containers - a LD3 would fit inside nicely, though getting it up the ramp would require a winch and this Sherpa didn't have one, and the mounts for it were buggered. Perhaps lower the ramp onto the deck of the loading truck... The fellow importing this one into Canada will have a fight on his hands because it's a former military plane, not a true civilian model.
