Nice photos but at least two of those photos being spread on twitter and posted repeatedly were taken from other unrelated events in the past.
The second photo is from a Make-a-Wish rally in May 2013 where hundreds of trucks showed up in support of the Make-a-Wish Foundation.

The fifth photo is from a Super Rig Rally held in Joplin, Missouri June 5, 2012.
