So, in the same post, you said that charging off the engine was a bad idea and would’t work well, and that it works great and it’s what you do??

No what I said was that I would not leave my vehicle run JUST to charge the batteries. Charging while driving is a simple solution to almost free power. Leaving a vehicle sit and run a massive engine for a trickle charge is not wise.
