That's precisely the point....in a pinch, if done right, it can work. And you're limited to what a single 30 amp breaker in your house can handle anyway, which is, surprise surprise....7.2kW. So.... kill you main house utility breaker.... turn off/unplug EVERYTHING you can be without, plug in truck and likely get by running a couple of key lights, your fridge, etc.Hummm, you know, that seems like that should work in a pinch. Just throw the main breaker coming into the house and shut off everything you don't want to power up. The house ground may throw the truck cut off though. Guess that could just be undone for a temporary fix.
