I try to avoid hauling the shop out to the site.
I try to do the same. One time while fixing a voted system I had 2 service monitors (super heavy Cushman and HP 8920), 2 handheld radios, a TIMS, an oscilloscope, a bag of patch cables, a heavy toolbox, a Bird 43, a box fan, and a gallon of water. I took a picture of the whole setup crammed in a hot 8x8 room with 3 6' racks. Whenever the club would ask me to tweak it or fix it, I'd show the picture and ask, "Who's coming to help?" After a dozen no-shows, I told them to stick it up their ass. I just wanted help carrying the stuff up 2 flights of stairs to the roof.
