More Possible Transformers Vehicles Spotted in Texas

Below are two new images of potential Transformers 4 vehicles thanks to site reader Erik W. Last weekend, while in the Pflugerville and Manor area (in Central Texas), he and his son spotted the big semi truck hauling three black off road looking cars that are not identical but similar looking to each other. He was able to spot them turn at a yellow sign that said E7 with arrows and other markers. The "E7" signs have been used in the past to identify Transformers production's base camp for whatever location they happen to be at and sometimes shooting locations. The location beyond the suburbs of Austin so can't help but wonder if related to the TF4 farm set.

So what are the vehicles for? A few possibilties come to mind. Since black SUVs tend to be Hollywood short hand for government, these could be off road version, possibly part of Harold Attinger's (Kelsey Grammer) crew. When not goverment, black vehicles just means bad guys so Decepticon alt modes? Or they simply serve the practical purpose of being rigged for the camera crew to film action scenes. I guess NEST is another possibility but I don't think they have a part in this movie. However I have no info to back that idea up. As always time will tell.

Update: Two things: 1) corrected the location typos (no clue how managed to screw up both of them) and 2) from the comments it appears on the vehicles is nearly identical to one used in Revenge of the Fallen and the other has been ID as a Rally Fighter.
