In PA there is an annual required safety inspection, while the drums are removed it is a simple job to do an adjustment after they are put back in place, no need for automatic adjusters if one does proper maintenance.
PA mechanic is only required to pull one drum and inspect condition on each side during inspection on multiple axle trailers.. Single axle, sure the mechanic can adjust both since they are supposed to pull both.
Have run into a few lazy mechanics that don't bother pulling drums and they use an adjuster tool to adjust the brakes.. Not impressed with that procedure since the Mechanic that inspected my flatbed trailer BACKED OFF the adjustment on one brake on the passenger side of the trailer :M as I discovered by pulling all drums a day a go..
Have to be extremely careful adjusting brakes via the back hole, non self adjusting drum brakes do not have anything to prevent you from accidentally backing off the adjustment think you made them tighter.
Self adjusting auto drum brakes had a spring loaded lever that engaged in the adjuster star wheel that made it easy to tell if you were backing it off as the lever would catch and hold if you tried to back it off.
