I think you are onto something. I have had a problem with how "green" people think electric vehicles are. A lot of toxic gick goes into making batteries, and if you are charging on grid what gick was involved to get you the electrons for your EV. And it seems that every battery I know of or owned, once it starts being used, is dying and will have to be disposed of and replaced someday. Not very permie sounding. It would seem that using reliable gas burner, like your jeep, would be a good homestead option. Easy to work on, could easily stock pile a lifetime of parts and in a pinch even brew your own fuel.
Where did you get the gin pole rig on the back of it? How does it work for you? I assume you loaded those logs with it, did it easily make it a one-man job?
Electric chainsaws may have there place for limbing and other lite work, but we used one to fell a fair sized maybe 20 inch diameter tree at a PDC and it was hopelessly underpowered to the point I thought it was a bit unsafe using it, as it would "overload" and quit just when you needed torque. For any serious logging or firewood collection I would still give the edge to a noisy gas chain saw. Small engines are really not that complicated to diagnose and work on, and again you could easily stockpile a life time of parts and make your own fuel if it got to that.
