I'm just getting caught up and I'm 30 minutes in, about to shut it off. I don't understand introducing the prepping consultant, and then dismissing him as a nutcase when the whole premise for the episode is surviving the apocalypse. They didn't build the car at all, Tanner drove around in an MRAP, Adam stood in a field and shot nothing, then decided that a "weapon" that could not be aimed and didn't do any damage was better, and Rut did nothing at all. They then see a car, make some secret plans, and later there's a car completely done. At least they could have faked an amusing montage in a shed.
The GPS segment is so fake I may as well go back to watching Adventure Time. There's no way they would be allowed to drive through a populated area with no lights and blacked out windows. The "GPS" has some funky useless overlay, and they claim to not know how fast they're going.
The constant electric fence gag got old, the person touching the fence never seemed to be affected by it, just Tanner. Now there's smoke that's clearly added in post-production.. shutting off.
