I couldn't find anything on range when towing though.
Tesla Finally Has Its First Semi-Truck and It’s Already a Hit With Truckers
Innovations including a centered driving position, fast charging and a 500-mile range are winning over drivers

Tesla plans to begin shipping mass-produced Semis this summer from its Nevada Gigafactory after years of delays.
The first time Dakota Shearer drove a Tesla he took a wrong turn just outside Sparks, Nev., and got stuck on a bend that was too tight for his 40-foot trailer.
Normally, Shearer would reverse out of a jam by getting out of the truck several times to check his position in the road. But Shearer was seated in the center of the cab, eliminating the right-side blind spot, and he was flanked by screens showing every object around his tractor-trailer.
“I backed right out of there, no problem. It’s like I’d never done it in the first place,” Shearer said. “That right there showed me that the technology the Tesla has makes a big difference.”
Shearer is among the few American truckers to drive a pilot model Semi.
The Semi, by contrast, can travel 500 miles on a single charge, according to Tesla. For King Fio that means two or three round-trips a day from Long Beach to warehouses in the nearby Inland Empire or a single round-trip to Las Vegas. She has 20 Semis on order.
Tesla produces two Semi models with ranges of 325 miles and 500 miles. The company hasn’t publicly stated how much the Semi will cost and didn’t respond to requests for comment. Companies that ordered the vehicles are bound by nondisclosure agreements. But people familiar with the orders say they come in at under $300,000, or about double the cost of a diesel truck.
Battery-electric trucks have fewer moving parts than diesel engines and don’t need regular servicing.
He said the Semi pulled a 25,000-pound load of dog food up a mountain pass as though it wasn’t even there. He loved the smooth acceleration—and the attention.
