I think it's terrific that the OP is excited about the future of Evs. Although I don't agree with 'his' thoughts on timeline and obsolescence, his adoption and enthusiasm of the technology is critical for much needed change.
And for sure change is coming to transportation. For eg. BC Ferries has 6 hybrid ships coming (diesel electric). First one has completed sea trials and is scheduled to start service early next year. Harbour Air, a local commercial airline, plans to convert it's entire air fleet to electric with reduced maintenance costs mentioned as a major benefit. Had their first test flight recently on a converted 62 yo Beaver air frame. Over on ADV there's a tread on Yukon Gov planing to install charging stations along the Dempster. (altho I note, the promised BC to CA Hydrogen Hwy never happened)
I love Old Crow's post about the couple towing cross country with an EV (and thanks for the trailer mfr plug 
). What a great idea to plug in at CGs. Many have substantial electric service, perhaps there could be an opportunity for drop in charging. Funny, I suspected a fellow camper might have been charging in a CG we stayed at, on Fogo Island of all places. They had a fair sized teardrop as well.
Sure, the above scenario not work for the current, "but then I can't do what I do now" truck + camper guy. For the rest it might be an alternative way of recreating. Nothing saying we're going be able to continue doing what we do now. I mean, at some point the climate has got to matter. Or, matter in a way that impacts what we'd like to do. Who knows what may be coming in the way of restrictions, changes to access or added costs.
I do like the idea of the second household vehicle being an EV. Would have liked that personally but we continue to hang onto our old car rather than replace it. I think a PHEV could be great for a commuter / weekend warrior, only wish the mfrs would package the feature on more basic equipped models.
That said I do wonder if, at least in my area, this might already be in the golden time to own an EV. There are still purchase subsidies (now cancelled in another province) and charging has been free in some locations. My local grocery store had 2 spots installed in the parkade ~2 years ago. That worked great for the few. Recently another 2 were added. Those are well used now. Going forward I can imagine how more demand is going to be a headache for both the store and their customers. I already pass on cheap gas if there's a crowd at the station - too much potential for agro. I could charge at home in a garage but in my area a lot can't. And the future here is high density housing, some in car less developments.
Finally, back to the OP,
Manufacturers are not quite there yet but they certainly are racing in fast. Two, three years maybe.
...
What do you all think? Would you still buy an ICE truck or wait and see what happens with electric?
If I wanted to buy a camper truck right now I go with known, ICE. Concern would be that, "two, three years maybe." could turn out to be 5, 10 years. At my age that's too long, BTDT. Now, if I was 20 yo, maybe. But then again if I was 20 I might not even drive ! I might be part of a group that leap frogs EVs and goes straight to no vehicles.
The future is famously had to predict, I claim no special insight. I'm not much of a gambler but looking at the news, Victoria Falls, whats been happening in Australia, their Federal Gov response, Madrid, I don't see waiting being a very good bet. I figure run with what ya got and go now !
