I remember a story doing the rounds during the late 60s. One of the vehicles that the Argosy was supposed to transport was a fuel bowser, for those that remember, the one with the oval tank. It fitted fine but it was found that the Argosy floor was not strong enough. The floor was strengthened to suite, guess what, the strengthening was added above the existing floor which meant that there was now not enough height clearance to get the bowser on. Ho-hum.
