freaking A/C questions

IMO the main mental errors made by newbs are the assumptions that:

  1. it is normal to have A/C in a vandwelling context

  2. having a big inverter means you have an endless source of power

Here’s the most recent example from a user’s first post:

Vehicle: 2003 ford e350 5.4 gas high top extended full windows -mainly what i want from this electrical system is to be able to run a 5000btu window air conditioner through a 2000watt modified sine wave inverter through the night

Nope.  I’m not going to respond to those anymore.  I’ve been skipping a bunch of replies lately;  feels like Sisyphus pushing the same unrealistic expectations up the hill day after day.
