Continuity mistake: When Gus is showing Walt the lab, the washer leans forward with one item hanging out. Camera cuts and 2 items are hanging out. This is an instant cut and no time for the item to fall into the position. (00:21:20)

Other mistake: At an RV park, Hank is investigating an RV that looks like the one he saw in the pictures from the ATM camera. Desperate for a vantage point, he goes around to the back of the RV and starts to climb up the ladder on the passenger rear side of the vehicle. This RV is not supported at this time in a permanent fixture, as it's revealed shortly there after that the occupants were just on vacation. So Hank's full body weight getting on the back corner of the RV should have shifted it on it's suspension and alerted the people inside that something was going on far sooner than it did.
