I actually have to agree with DM's defence on this one. The trucks spotted on the video at 9:05pm, 9:15pm, and 9:20pm are all TB's truck IMO. Same overall profile, same running lights, same shiny rims, same chrome running boards, etc.
The fact that the video times don't line up perfectly with the cell tower ping times is simply due to a slight time discrepancy between the two sources. If they're out by just a few minutes, then all of the evidence lines up perfectly.
This is revealing one of the major holes in MS's story, and I'm glad to see that MS is getting called out on it.
