Why Tesla's are bad at towing!

1. Range with how much weight?"

Weight really isn't important. It takes very little power to keep weight moving. Just a little extra tire flex. Where vehicles are hurt by weight is when brakes have to be used to take energy out of the system for stopping and speed control.

More weight actually tilts the scale in favor of an electric truck since it can use regen to recapture about 90% of the energy that would normally be lost to braking.

The real issue on long trips is air drag. This concerns me more because the range of the pickup is given without a trailer. The truck itself is very aerodynamic. This means that a typical trailer with little or no thought given to aerodynamics is going to be felt much more than it would be behind a regular truck. It is going to be interesting to see how much impact trailers have on fuel economy. It might even be worthwhile making the bed cover come straight back from the high point to reduce the amount of wind hitting the trailer.

"2. Acceleration with 80k pounds. How much is profit generating payload not the extra weight of batteries?"

This depends a lot on what you are hauling. My understanding is that a large percentage of box trucks on the road are limited by volume, not weight. Walmart is a big early purchaser and I know that their trucks are generally pretty light. Battery powered trucks should qualify for the weight bonus given to trucks with an APU since they also have eliminated main engine idling.

1. Sure, maybe going downhill or flat. I will wait for the evidence that pulling a combined 80k takes an immaterial amount more energy than pulling empty.

2. So you agree pure marketing BS.
