The Russians Are Coming - S1-E6
Plot hole: Del and Rodney find the nuclear shelter and decided to try it out. They then do a couple of runs to find the best place to build it. We then see the pair inside the nuclear shelter which they have built, filled with stuff like a bed, food batteries etc. all in one afternoon. (00:11:45)
Suggested correction: No reference is made to what day it is. There is nothing to suggest that the practice run and the scene inside the bunker happen on the same day.
Apart from all of them wearing the exact same outfits, Del mentioning that it needs to be back on the building site by Monday when having a weekend to try it out. All points to it taking place over the course of a day from the start of the episode to the end.
When Del refers to "it" being back on the building site by Monday morning, he is actually referring to the chemical toilet that he's acquired. He is not referring to the shelter as this was under a pile of bricks on a demolition site not a building site. Del has already assumed ownership of the shelter due to finding it under the pile of bricks he has purchased.
