Sorry to dissappoint you all, but this 'series' of photos (now put to music) are photoshopped. These images have been 'floating' around, (pun intended) for years.
Although the first truck did, in fact, tumble into the drink, the second truck did not, and was not ever in danger of doing so. You will also see photos of the second truck actually 'in' the water. These are fake also.
I have the original series of 10+ photos and it is clear to see that the vehicles in the background and the people standing in different locations do not match the natural timeline of the recovery events. The second truck recovered successfully both the white sedan and the original truck.
Sorry.
