The data

Real-world EV towing data, logged mile by mile.

The most comprehensive real-world Rivian R1T + Airstream towing dataset we know of: every mile, kWh, charge stop, and foot of climb, logged off the dashboard, not projected. 30 of 31 days and 44 tow segments so far, and growing every trip.

Rivian Roamer, most miles towed
#1 all-time

* 4,405 mi towed on this trip. All-time towed on the current R1T: 8,697 mi, from the Rivian Roamer leaderboard (refreshed every 2 hours).

Towing efficiency is miles ÷ kWh from the pack, weighted across every logged segment. Range estimate = 1.19 mi/kWh × 141 kWh usable. Updated on every deploy.

Rig performance, real-world towing

What the rig is actually doing on the road.

Every number below is logged from the Rivian's own dashboard with the Airstream attached. No projections, no manufacturer figures except the 141 kWh usable pack capacity used in the range estimate. Updated as each day's data lands.

  1. 177 mi

    Furthest tow between charges

    Mount Pleasant IA Tesla SC → Columbia MO RAN

  2. 1h 40m

    Longest charging session

    Gila Bend RAN, 139.79 kWh added

  3. 12,209 ft

    Highest altitude while towing

    Day 22, Rocky Mountain National Park from the Lyons basecamp

  4. 13,700 ft

    Most climbed in a day towing

    Day 25, Denver → Grand Junction, CO (over the Rockies)

  5. 16,450 ft

    Most descended in a segment

    Day 25, Denver → Grand Junction, CO (over the Rockies)

  6. 2.35 mi/kWh

    Best efficiency while towing

    Boulevard KOA (pickup) → El Centro Tesla SC

Data as of the 2026 San Diego → Chicago trip, updated daily. Range is weighted-average across all logged tow segments × 141 kWh, not best case. Headwinds and grades pull the realistic number under that figure; downhill stretches like the I-8 drop into Imperial Valley pushed the best-segment number well above it.

What moves the needle

What actually changes our towing efficiency.

Same truck, same trailer, the mi/kWh still swings hard day to day. Here is how much of that is the wind, the grade, and the heat, measured across every single tow segment, not guessed.

Wind

worth 0.3 mi/kWh (27%), a 42 mi range swing on a full pack

Tailwind 1.40 vs Headwind 1.10 mi/kWh

Grade

worth 0.17 mi/kWh (16%), a 24 mi range swing on a full pack

Rolling / flat 1.24 vs Net climb 1.07 mi/kWh

Temperature

worth 0.23 mi/kWh (23%), a 32 mi range swing on a full pack

Mild (70–85°F) 1.25 vs Hot (>85°F) 1.02 mi/kWh

Charging networks

Where we plug in, and what it costs.

Every charge on the dataset, grouped by network: the paid DC fast-charging plus the campground 50A pedestals we sleep on, with cost per kWh, peak speed, and how much energy came from each. Free Rivian Adventure Network charging has saved $995 against list price so far.

Network Sessions kWh $/kWh Peak kW Avg kW
Rivian Adventure Network 25 2,018.8 $0.49* 223 107
Tesla Supercharger 21 1,265.5 $0.40 198 114
Campground 50A 13 969.9 incl.† 7.7
IONNA 5 530.8 $0.39 220 149
Electrify America 1 97.3 $0.61 80

Peak kW is the fastest charge rate we caught on the Rivian display or the charger screen for each network, not the network's rated maximum. Some networks are sampled more than others (RAN and IONNA most often), so a lower peak can mean a genuinely slower charge or simply fewer screenshots.

* List price. We paid $0 on the Rivian Adventure Network through the Rivian referral perk, free DC fast-charging you can get too: wattreach.com/rivian.

† Overnight Level 2 on the 50A pedestal at full-hookup campsites, charging while we sleep via the Rivian portable charger on a 14-50 outlet. The energy is included with the campsite fee (no per-kWh charge), and several early-trip kWh figures are estimates from state of charge. Slow by DC standards at 7.7 kW, but it is why the rig leaves most campgrounds at or near 100%.

Gear we run

What's actually on the rig

The pieces we genuinely use and would buy again. Links go to where you can find them.

  • Starlink

    Internet wherever we park. The only connectivity that has reliably kept up off the grid, and what the Apple TV and the work-from-camp days run on.

  • NEMA 14-50 EV charging adapter

    How the Rivian sips off a campground's 50-amp pedestal overnight when there is no DC fast charger nearby. The quiet hero of the no-RAN nights.

  • Apple TV 4K

    Lives in the Airstream and streams over Starlink, so the setup travels with us instead of fighting whatever screen a campground has.

  • JL Audio

    The stereo gear behind the bunk-area remotes. Clean sound for the long quiet-mile stretches.

  • RV USB-C outlets

    Wired throughout the cabin so phones, cameras, and the action cam all charge without a brick of adapters.

  • AirKrafters mats + trim

    Airstream-specific door mats and stainless exterior trim that replaces the factory plastic. Brand-direct, not on Amazon.

Rig FAQ

Questions about the rig

The truck, the trailer, the weights, and why we tow with this setup.

What truck and trailer does Wattreach tow with?

A 2025 Rivian R1T Tri-Motor Max-Pack (141 kWh usable, about 850 hp, ~420 mi unladen range) pulling a 2024 Airstream International 23FBT, a 23-foot, twin-axle, polished-aluminum travel trailer that runs about 5,000 lb dry and 6,000 lb fully loaded. Real-world towing range with the trailer behind it is about 180 miles per charge.

How much can a Rivian R1T tow, and how much does the Airstream weigh?

The R1T is rated to tow 11,000 lb. Our 23-foot Airstream International loads to about 6,000 lb, well under that ceiling, which is why the three motors never labor and the truck handles crosswinds without drama. The trade is range: a trailer roughly halves the unladen number.

Why a three-motor Max-Pack instead of a smaller battery?

Towing eats range, so the largest pack (141 kWh usable) buys the longest legs between charges, 100 to 120 miles while towing instead of 60 to 80. The Tri-Motor drivetrain adds the torque to hold a loaded trailer up a grade and the regen to brake it back down a descent without touching the friction brakes.

What Airstreams and Rivians came before this rig?

Three Airstreams: a 2016 Basecamp 16 (fiberglass-front, ~3,500 lb), a 2020 Caravel 20FB (~4,500 lb), and the current 2024 International 23FBT (~5,000 lb dry). On the tow side, a Gen-1 R1S started it all, then a Gen-1 R1T Dual-Motor Max-Pack (bought back by Rivian after repeated rear-motor failures), now the Gen-2 R1T Tri-Motor Max-Pack with 18,000-plus towing miles on it.
