Yeah, pretty much, I can think of many downsides too if I want to pick holes at this stage, but like your dads advice, I will roll with it, prob because I have an electrical background and understand all the aspects.
Electric is not without cost or pollution, people need to ack that, but short to medium & even long term, using the suns energy really is a good idea, and if it runs out nothing will matter anyway.
To be frank, the US and West should keep oil as a backup, backup for war or if we have a nuke winter or other event that reduces what we get from the sun temporarily. I do think that has been the US position for a while, but, EV should be transitioned to ASAP, it is finally happening.
Anyway, the scout probably would be a good thing, if not too expensive.
My only issue with cars or small AWD 4WD vehicles and EV is water, water is bastard where electrics are concerned. The mechanics will remain busy I suspect.
