The Andovers did use it
Herod ... I was Wessexing there a little later than you (70-71) and can recall them (84) dropping off some fuel drums for us (78) on an exercise.
Somewhere in the loft I may even have pictures .... but that's yet another post-retirement project!
And of course it was on the route of the (in)famous Masafi-Bithna resupply run for the TOS .....
...... where the highest obstacle was the Stimm Bar
