The day

  1. start

    Amarillo KOA Holiday, morning departure

    8:12 AM departure from the Texas-themed KOA, trailer unplugged from its 50A. The park does not allow charging the truck (told not to plug it in at check-in), so the Rivian rolls out on what it had and the first charge of the day is the Buc-ee's Tesla SC, 5 mi south. Trip B reset reads 119.1 mi at 1.45 mi/kWh for the Tucumcari → Amarillo evening leg (82 kWh). Cold start at 51°F.

  2. charge

    Buc-ee's Amarillo Tesla Supercharger

    8:35 AM arrival, 5 mi south of the KOA. 85.84 kWh in 58 min on a 325 kW Tesla SC, $30.04 paid ($0.32/kWh + 8.25 percent Texas tax). The Buc-ee's store next door is its own attraction: Chinese-made I LOVE AMERICA t-shirts and Buc-ee's-branded flip-flops with the smiling beaver mascot tag, a wall of jerky and Beaver Nuggets, brisket-on-a-bun. Came out with mesquite-peppered beef jerky for the road.

    U-Drop Inn, Shamrock TX

    Headwind on this leg 18 mph from the ENE Descends this leg −950 ft

    12:41 PM at 105 N Main St. The 1936 Art Deco Conoco station + Tower Conoco Cafe, restored in green-glazed tile with the cream Art Deco tower and Texas-shaped "U DROP INN" neon. The building is the visual inspiration for Ramone's House of Body Art in Pixar's Cars (2006). Today the property is the Shamrock Visitor Information Center + Gift Shop. Quick photo + visitor-center swing, ~25 min on site.

  5. charge

    Erick OK Electrify America

    Headwind on this leg 18 mph from the ENE

    1:21 PM plug to 2:34 PM unplug (1h 13m) at 901 N Sheb Wooley Ave at the Love's Travel Stop (Sheb Wooley, the Erick-born country singer/actor). 97.28 kWh delivered at an 80 kW average against an "UP TO 350 kW" pedestal stencil, a steady derating across the whole session. $0.56/kWh + 8 percent tax = $59.79, the most expensive charge of the trip and the slowest by a wide margin. We had no choice: the I-40 stretch from Buc-ee's Amarillo to the OKC RAN is too long for the rig to skip a midpoint, and EA was the only viable non-Tesla option on the route. Trip B from Buc-ee's on arrival: 116.0 mi at 1.15 mi/kWh towing (100 kWh used). Trip B was not reset at unplug, so the next leg's numbers cumulate through the OKC arrival.

    I-40 east through central Oklahoma

    Headwind on this leg 18 mph from the ENE

    Afternoon push from Erick through Sayre, Elk City, Weatherford, Clinton, El Reno. Red dirt country, wind turbines on every ridge, the OK 152 / I-40 split west of OKC.

  7. charge

    OKC RAN, west OKC

    Headwind on this leg 18 mph from the ENE

    5:24 PM plug to 5:57 PM unplug (33 min) at 7624 West Reno Avenue, pedestal 1A. 94.31 kWh delivered at a 213.18 kW DC peak. Listed at $0.47/kWh ($44.32) and refunded to $0.00 by the Rivian referral "Complimentary charging" perk. Coasted in at 2 percent SoC / 7 mi of range, the closest we have cut it. The Rivian pedestal pulled 2.7x the peak rate of the Electrify America stop that put us in this state and would have cost 84 percent of what EA charged us, before the refund. Erick → OKC RAN segment ran 136.7 mi at 1.20 mi/kWh towing (114 kWh used), derived from the cumulative Trip B reading minus the Buc-ee's → Erick leg.

Charging plan

Where the electrons come from

  • Tesla Supercharger

    Buc-ee's Amarillo Tesla Supercharger

    9900 I-40, Amarillo TX 79118. 325 kW DC Magic Dock-capable stalls at the Buc-ee's mega-station, ~5 mi south of the Amarillo KOA. Charger S/N GF22511500099M, $0.32/kWh plus 8.25 percent tax. The store inside is the full Texas-roadside experience, brisket sandwiches and Beaver Nuggets included.

  • Electrify America

    Erick OK Electrify America

    901 N Sheb Wooley Ave, Erick OK 73645 at I-40 exit 7 (the Love's Travel Stop). Charger 100129-02 Love's 253. The "UP TO 350 kW" stencil on the pavement is aspirational; we got steady derating, 80 kW average across the 1h 13m session. $0.56/kWh + 8% tax = $59.79 paid (the most expensive charge of the trip). We took it because the I-40 stretch between Buc-ee's Amarillo and the OKC RAN is too long for the rig to skip a midpoint.

  • RAN charge Rivian Adventure Network

    OKC RAN (west OKC)

    7624 West Reno Avenue, Oklahoma City OK 73127. Pedestal 1A (Charger ID US-4HC-3BP-1A). 94.3065 kWh in 33 min 19 sec at a peak 213.18 kW DC. $0.47/kWh list rate fully discounted to $0.00 via the Rivian referral "Complimentary charging" perk. Coasted in at 2 percent SoC; the 213 kW peak here is roughly 2.7x the 80 kW average we just got at Electrify America for a third of the time per kWh.

Common questions about Day 06

Is the U-Drop Inn really the inspiration for Ramone's House of Body Art in Cars?
Yes. The U-Drop Inn at 105 N Main St in Shamrock, Texas (built 1936) is a National Register of Historic Places Art Deco Conoco station with a cream tower, green-glazed terra-cotta tile facade, and the iconic Texas-shaped "U DROP INN" neon sign. The Pixar Cars (2006) team toured the building during pre-production and used its tower + glazed-tile geometry as the visual reference for Ramone's body shop in Radiator Springs. The property is now the Shamrock Visitor Information Center + Gift Shop and is open daily; trailer parking sits in the wide gravel lot adjacent to the canopy.
How does the Buc-ee's Amarillo Tesla Supercharger work for a non-Tesla EV?
The Tesla Superchargers at the Buc-ee's Amarillo location (9900 I-40, Amarillo TX 79118) are 325 kW DC stalls open to non-Tesla EVs via Magic Dock + native NACS. The Rivian R1T Gen 2 has NACS from the factory; plug in like a Tesla. Pricing on our 5/19/2026 session ran $0.32/kWh + 8.25 percent Texas sales tax, which came out to $30.04 for 85.84 kWh. Session time 58 minutes from 20-some percent SoC, charger S/N GF22511500099M, Invoice #3000P0309083620.
