At 7 lbs a gallon for diesel most semis can carry 200 gallons so add an extra 1000lbs if you like, the Tesla still has to make up 5000 lbs while having 1/3rd the range.
Timing stops for megachargers will be a whole lot more difficult than truck stops until they are as ubiquitous. If you have to use a plain old supercharger your talking 8-10 hours for a charge, don't even bother with a normal plug of any kind.
That's with a megacharger not a supercharger, there are no megachargers deployed anywhere yet. Megachargers are 1600 kilowatts vs 120 kilwoatts for a supercharger.
A charging station with 10 megachargers going at the same time will draw as much power as a small city of say 10,000 homes.
Is that possible? Assuming 500 miles of range at 2kwh a mile is a 1000kwh battery, charged over 30 minutes, is 2 megawatts, if the voltage is the same as the supercharger (480V) requires 4000 amps...
Yeah no doubt, there are a ton of unanswered questions here. If they can't retrofit their existing chargers to "mega" status that would pretty severely limit the usefulness of this product.
At least the weight will be (measurably) consistent no matter how much charge is in the battery. That said, they still weigh more than diesel so I assume they'll pay more at the scales.

I'm not sure what you mean here. In the US, scales are used to ensure compliance with axle load limits, not to determine any costs.
In any case, since they don't need the weight of a diesel engine, transmission, fuel tanks, or emissions systems I'm not sure how the weight balance will work out.
What's required for a sleeper cab? We got some shots of the interior and it looked easily big enough to add a bed or the like. With a battery that big heating overnight should be practically free.
