Here's the thing, there's never going to be convincing evidence for you to decide that it wasn't what your hunch said it was. That's the nature of suspicion.
You could Google "national plant services van" on image search and find similar vans, and that the company is owned by is the Carylon Corporation, with revenue of $300m/year -- but that couldn't convince you that a government agency (it wouldn't be the NSA unless they're violating the law) didn't borrow it or copy it.
You could read that their services include "Digital CCTV inspection. Laser profiling. Sonar pipeline inspection." but that couldn't convince you that the monitor+joystick and other equipment is needed for sewer inspection, because you already believe it is for surveillance. (The irony being that the kind of mass surveillance Mark Klein exposed, or Snowden exposed, means there's absolutely no need to park a truck outside someone's house. You can track who they're communicating with already, and you can subvert their own devices to listen in, instead of parking a van out front for their neighbors to notice.)
You could look at who has the contract to inspect sewers in your town -- it's public record. But you could still choose to believe that the federal government did the same check, and went out and got an identical truck so as to be less suspicious (although in this thread half the people are saying "that's too clean/fancy/technological to be a sewer inspection van!" so if they did it would have backfired.)
Was he under surveillance? Who knows. Does this truck prove anything either way? No. Everybody is going to leave this thread with whatever hunch they came in with.
