When the Doc pulls up and the Dukes take his bus over, everyone jumps in the bus. The door on Daisy's car is open. When the bus pulls off after the bad guys, who closed the door?
Towards the end of the episode when the Dukes run the 3 con artists off the road with the RV and the crooks car flips, you can see the ramp in which they used to make it overturn.
Harkness: Mr. Cooter, sir, how bad is it?
Cooter: Real bad. If it was a horse, we'd have to shoot it.
