Easy question first.  The loader either walked along side, or road the pig.  He could also duck inside.  There was a magazine just below the rear hatch, accessible only from the outside.  I believe some rounds could be carried inside too.
The 106 were set on two banks, left and right.  They were bore sighted, also.. there was two 50 cal spotting rifles, one for each bank. The bank had three 106s.  After bore sighting, the 50's were aligned with the 106's.  I hope my memory is serving me right.  I will think some more on it, and see if anything else pops in my mind.  
I am not sure what the pay loard for mules were,  but they were designed for hauling a lot of stuff.  Never got to play with one.  When I arrived in-country, the Ontos was gone..

 Since you appear to have some experience with the 106, I wonder how the hell the Ontos guys zeroed those six 106's.  I also wonder who was the poor fellow who had to get out of that Ontos and load those six 106's.  Must have been a PVT.
