I guess this is my worry with the Cybertruck for me personally. And I'll preface this by saying every vehicle isn't for everyone. A Mazda Miata is a great vehicle, not so much for a family road trip.
While it looks like the truck could be their best deal for a lot of people, I use a pickup truck for my summer camping and that's about it. Most of the trips are 2-3 hour drives, 100-150 miles, and a few every year up to Duluth and such which are 225 miles or so away, and a couple big road trips (1000 mile or so). It's nice having it for hauling
My camper is a decent sized one, 8000 lbs loaded, not aerodynamic. So on my truck, my MPG cuts in about half (gas half ton). While electric might be more efficient towing, a lot of that trucks efficiency is in it's drag coefficient, which my trailer would throw out the window.
I know if I go places with electric, that will help me out, but I'd lose my ability to go non-electric (run a small generator and camp dispersed and middle of nowhere). But even with the electric sites, in summer, that would mean no A/C at night while charging which is kinda the point of paying for electric.
Also, the supercharger setup on those road trips. I heard they will be making pull through superchargers, but until I see them I'd rather wait.
Anyways, I see a video claiming 1/3 the efficiency here, and my pickup gives about half. So using those numbers...
250, 300, 500 mile ranges for the 3 models...
That's 83, 100, and 167 mile ranges with my camper at 33% efficiency, and 125, 150, and 250 with the 50% drop. Figure usable range of that (not driving to empty) and it's not too far on a family trip. For towing a boat, popup, or those who camp nearby at the same lake all the time, towing a trailer of junk to the scrapyard or dump every now and then etc... maybe, but I want to see real world there before making that call. And with myself, camping northern Minnesota is pretty desolate. If I'm going somewhere without electric I can unhitch my pickup, drive into the little lake town down the road, gas up and be good. A bit tougher relying on a supercharger off the beaten path.
So for me, it might struggle with the one thing I'd truly want a truck for. I guess that's my one reserve of why I'll be pursuing a model 3 as the family car, but holding off on the truck... for now. I might just sell the camper and go back to tent camping (and I've done the truck tent and had a blast) too, in which case, it moves up as more viable for me.
But again my situation is probably different from a lot of peoples. Most truck owners aren't using the towing feature of their truck often at all.
