For use at home, battery saws are great. If you take it to the hills, you need a generator. It all depends on how you use it.
A couple batteries and an inverter for the truck. I'm warming up to the idea of "needing" one.

If you work 40 hrs/wk: at 5% inflation and after 5 years, you need a 28% pay raise or to work 44 more hours (*one full extra week* per month+) to make up the difference.
