Doesn't matter how efficient it is. This is being sold as a truck. As a truck, it needs to do truck things. If it can't, then it is an SUV with a bigger than average trunk. That is OK, but lets not pretend that an EV that can't perform Truck things is a Truck.
250 miles towing or hauling 50% of max capacity is a min range. If it can't do that, then it is not a truck. If you only use your vehicle to tow 50 miles that is fine too but you can get by with an SUV now. I can not and am looking to buy the first EV truck that really can do truck things. I'm hoping it will be the Cyber truck. If not I may have to wait on the RAM. They are promising more range in their vehicle and may beat the cyber to market.
I understand your position, but prepare to be disappointed for the next decade. That's just reality.
As a business owner I genuinely 'need' a truck, hauling dirty/ large crap daily. That said, I don't need to trailer heavy things long distances and I think this statement is true for a majority of modern truck buyers.
The minority however, that has to tow heavy items long distances with regularity, will have no choice but to stick with ICE for another decade or 2.
Good luck!
