It's the angle of the view. A/C units are always centered side to side on modern RVs. Usually in-line with roof vents. It's rare they're offset to one side or the other. They do move front to back depending on the make/model/length. Some have two or even three A/C units.
OK.. The A/C might be the same. There is also a round maybe cell antenna with the one in the parking lot. You can see it to the left of the ladder in the back. On the roof seems to centered with the three driving lights. It’s not on the bomber RV. I will also assume the speaker we can see in the bomber RV was added close to the time of the attack
