The longer answer is it really depends on the band and the venue. (IMHO) Smaller independent bands especially like to put big speaker sets and amps on their riders, even ridiculous things like 2 line arrays for a 200-person concert in a small inclosed space. These days, once you get up to the Van Halen-sized concerts, you'll find a lot of professionalism. For smaller concerts (< 600 guests), you make it work with what's the venue can get and do the best you can, really. If it's a for-profit show, and the venue knows what they're doing, they'll rent some gear (especially amps). Usually the mixer and speakers in the venue are considered 'good enough' for budget reasons.
Also, note that they brought 9 tractor-trailers... that would be a low number today, try doubling that for big tours these days.
