Cold Tire Pressure: Front 50 psi, Rear 65 psi, Trailer 80 psi Truck Passenger Weight: 350 lbs Jamie drove from Oceanside, California, to Temecula and back, maintaining speed limits on ancillary roads and setting cruise control at 60 mph on the freeway. The temperature was 68 degrees Fahrenheit, and the climate control was set to 72 degrees. With an altitude change of roughly +/- 300 feet, he attained 778 Wh/mi, resulting in a full battery range of just 157 miles when towing. "It pulled wonderfully," Jamie noted, though he did encounter a software glitch: The traffic screen thought there was a large truck behind me (it was the trailer) and kept flashing a picture on and off every half second. That was very annoying, an issue that needs to be addressed in the software. The Range Is a Big Concern Advertising Despite this, he praised the "software trailer brake actuator," saying it "works well. Overall, it is an incredible experience, but the range is a big concern." Jamie had been willing to invest an additional $16,000 for the auxiliary battery to gain more range. Confirmation of Cancellation Reports from reputable sources confirm Tesla's decision. Kelley Blue Book stated, "In a move rumored since early last month, Tesla appears to have ended plans to build a range-boosting second battery for its Cybertruck pickup." Electrek reported that Cybertruck owners have begun receiving refunds for the battery booster, accompanied by an email explaining, "We are no longer planning to sell the Range Extender for Cybertruck." KBB detailed the promised solution: "Essentially a second battery half the size of the first, it would mount in the Cybertruck's bed. It would occupy some of the truck's bed space, and only Tesla technicians would be able to install or remove it. But it might boost the truck up to a more competitive range." A Costly Farewell Now, Jamie is faced with selling his cherished Cybertruck and finding a vehicle that can reliably pull his RV. He's considering traditional options, such as a Ford F-250 or a Chevy Silverado Diesel. The financial hit is significant. Jamie has invested over $2,000 in Tesla accessories and an $8,000 ALSET wrap that's in perfect condition. His additional upgrades include:
