Having said that, reading comments like this, I sometimes think it would actually be great cover. Because you have respected people, like yourself, unequivocally stating that it couldn't possibly be an NSA van.
But, to say it again, I agree that I don't think the NSA would need to do this. My above line of reasoning certainly doesn't hold too much water under serious scrutiny.
You can second-guess that, but I think past this point, we're reenacting the duel between Vizzini and Westley.
It's like the spies working in embassies that were easily detectable despite an elaborate cover because they used the car that the previous spy left behind when they went home.
So I guess the reveal is that it _is_ a real sewer inspection van, but the NSA has legitimately been inspecting sewers for years to innoculate themselves from suspicion?
I guess they must be down there looking for rodents of unusual size.
You can either disguise your operation as a goofy sewer inspection van and hope you trick every single person who notices it into second-guessing themselves along the lines of "surely the FBI would be more low-key than that..."
Or you can just be low-key in the first place, end of story. I assume the tech in the modern day (as compared to, like, the 80s when this trope was born) is advanced enough to facilitate this option.
Corporate ventilation. A wonderful thing. Everyone needs it. No one suspects it.
Or maybe it’s the aquarium guy.
No, those are the guys making meth.
Gotta love paranoia.
IIRC a hacked HVAC vendor was how credit card skimming software was infiltrated into Target and credit card data was exfiltrated a decade or so ago.

Shhhhh!
This is a false dichotomy. Federal agencies prove themselves to be fallible (even incompetent) all the time, they just have far more resources available to make up for their mistakes.
Multiple days would be suspicious but that would be true of even the “sewer inspection” cover van
in our country some spies got caught drivin around with wifi pineapple in plain sight circling govt and ngo sites.
in my mind thats next level dumb stuff, but maybe they arent really hackers and think its not conspicuous, or even the opposite, they know exactly what it is but think 'oh normal people wont stop to think about this, they dont recognise such equipment'.
if you werent there, didnt know the guys in the van etc. etc. - its all just guesswork.
even public record of a sewer inspection right then and there at that time (which i kinda doubt exists) wouldnt confirm or deny what that van was really doing there.
that being said, i would _assume_ its a sewer inspection van. but thats an assumption, not a known fact.
They either find someone who has suitable vans they can threaten with prosecution. That person then agrees to be an "informant" because that's better than losing your life to the feds and then their handler asks to borrow a van. They like this because no money needs to get spent specifically on it so it doesn't tend to get scrutinized. If they're going full above the table they register a business with the state complete with valid HVAC license or whatever and then rent a van from some company the FBI owns/runs that rents white vans and have some decals printed up. (For those inclined to do further reading, the OSINT hobbyists have done a lot to expose this workflow as it relates to aircraft so probably start there.)
Why bother mimicking a sewer inspection van when you can just buy or commandeer an actual sewer inspection van?
