Once again, I'm just here to throw off the averages, and give the guys something to show the wives who keep saying "you have too much gear".
Little system is generally all we do for weddings. It will run 10-12 trips in for speakers, 1 amp rack, 1 source rack, 1 cord box, 1 closet, somewhere around 7 light boxes (3 of which would each have a single 10' truss on top for transport).
In total, about 21-23 trips for the little system (depending on if we have space for just 3 or if we can do 4 dual 18's a side).
For the big system, add 12-14 more speakers, another amp rack, a crankup rack, 3 more light boxes and 4 more sticks of truss. so...I suppose a total of 40 or so trips for the big stereo. Probably not thinking of a few boxes that are in there. I could count friday I suppose.
