And you never never never run anything off your truck battery. That's for starting your truck. You need an isolator so the house battery doesn't drain the truck battery. And cordless tools suck. They have their uses but for doing work like ripping boards and cutting sheetgoods those battery powered skilsaws just can't keep up.

A few years ago, I'd have agreed with this.  But the times, they are a changin' when it comes to cordless tools.  They flat out kick ass now a days.

Still true for true professional level all-day slogging, just not practical to keep that many big batteries cycling, multiple chargers to keep them topped up, overall higher cost.

But for hobbyist / DIY use no worries

And power lights and fans as well! Cann't wait for my new 9 amp hour batteries to get here to see if it will keep my fan going 24/7.
