Which EV truck has the best towing range?

The honest answer depends on evidence level. Wattreach has measured the Rivian R1T across 4,405 towing miles at 1.19 mi/kWh. Cybertruck and F-150 Lightning pages include first-hand towing notes. Silverado EV and Sierra EV pages currently use official specs plus Wattreach Airstream efficiency math until we log our own segments.

Can I compare trucks by battery size alone?

No. Battery size sets the energy budget, but trailer shape, speed, wind, grade, tires, charge-port placement, and station layout determine whether the trip feels easy.

Why does Wattreach label evidence levels?

Because measured data, first-hand notes, photo evidence, and official specs are not the same thing. Labeling the source of each claim makes the comparison more useful and more citable.

EV truck towing range comparison

Compare electric trucks without pretending every number is the same kind of truth.

Rivian R1T has the measured Wattreach tow ledger. Cybertruck and Lightning have first-hand towing notes. Silverado EV and Sierra EV Denali get official-spec planning math until we log charge-to-charge segments with them.

Short answer

The R1T is measured. Cybertruck and Lightning are first-hand. GM trucks are currently planning math.

Our measured benchmark is 1.19 mi/kWh across 4,405 Rivian R1T + Airstream towing miles. The non-Rivian trucks are physically larger, less aerodynamic, and run less efficient motors and drivetrains, so their range estimates use a conservative 1.0 mi/kWh with the same trailer, not the R1T's measured figure, each with its evidence level shown.

That structure gives users the thing most comparison pages skip: which claims came from our own logged data, which came from a real tow impression, and which came from official specifications.

Airstream range planning table.

The range columns apply Wattreach's measured Airstream efficiency to each pack basis. Use them as planning math, then read the evidence label before treating any number as measured.

Truck	Evidence	Pack basis	Full-pack tow estimate	10 to 80 percent hop	Official source
Rivian R1T	Measured Wattreach tow ledger	141 kWh	168 mi	118 mi	Wattreach rig data
Cybertruck	First-hand towing notes plus photo evidence	123 kWh	147 mi	103 mi	Tesla Cybertruck specs
F-150 Lightning	First-hand towing notes plus trip photo evidence	131 kWh	131 mi*	92 mi	Ford F-150 Lightning specs
Silverado EV	Official specs plus Wattreach trailer math	205 kWh	205 mi*	144 mi	Chevrolet 2026 Silverado EV trailering chart
Sierra EV Denali	Photo-documented EV-truck meetup plus official specs	205 kWh	205 mi*	144 mi	GMC Sierra EV Denali specs

* The non-Rivian trucks are estimated at a conservative 1.0 mi/kWh, not our R1T's measured 1.19 mi/kWh. They are physically larger, less aerodynamic, and run less efficient motors and drivetrains, so with the same 23-foot Airstream they give up efficiency. The Rivian R1T row is our own measured figure.
