I wonder if you can charge the batteries while driving, if so, you could put a small generator in the bed and plug it in to help extend the range. A 4500 watt generator will run all day on 5 gal of gas with a 50 percent load.. They should also have solar panels built into the hood, cab and bed covers to aid in daytime charging.. An optional generator in the bed or frunk with a port that ties into the charging circuit that can charge while driving, sitting at a dinner while having a meal or overnight at a hotel while you sleep.. That's how they should be building these electric trucks to make them more flexible, then you could go camping hit the trails for a little off roading or tow a camper/boat without the worry of getting stranded... JMHO..
