A vehicle that has a towing capacity in the tens of thousands of pounds can have a big battery bank, and so it could have longer range than a small sedan. Of course the weight of the battery itself reduces range, and carrying a load will reduce range, and bigger batteries increase cost, but I suspect the reason Ford is introducing an electric truck in 2021 (and Tesla has one coming, too) is because they've done the math and it's finally starting work out right for some category of their customer base.
The truck market is downright scientific, and Ford is the leader in that market. They serve a lot of fleet customers and have huge amounts of data about how those fleets are used. They must have found a segment that will find electric vehicles cost-effective, otherwise they'd put it off another year or two or three. It's not the average truck buyer that's pushing them toward electric (there's a deep vein of stupid in that market that loves big, noisy, smelly, engines), but I'm confident they aren't doing it out of the goodness of their hearts. I believe Ford making an electric truck means there's a market for electric trucks, whatever their limitations, at the price they can deliver them.
