Six logged legs into late afternoon on Day 3. Rolled out from the Wellton I-8 rest area at 4:36 AM, ran 45.5 mi at 1.22 mi/kWh (37 kWh) into the Dateland Tesla Supercharger by 5:34 AM. After a 6 min top-up, 50.5 mi at 1.11 mi/kWh (45 kWh, 1h 0m at 50 mph) reached the Gila Bend RAN by 6:42 AM. After the 139.79 kWh RAN charge (8:23 AM departure), 48 mi at 1.26 mi/kWh (38 kWh, 1h 6m at 44 mph) up AZ-85 and I-10 reached Estrella Mountain Regional Park at 9:37 AM. Estrella to Phoenix Biltmore RAN: 31.6 mi at 1.19 mi/kWh (27 kWh, 55 min at 34 mph through metro traffic), arrival 10:59 AM. Phoenix to Sedona RAN: 111.1 mi at 1.06 mi/kWh (104 kWh, 2h 0m), the watts-burning climb up I-17 over the Mogollon Rim (peak 4,716 ft); pace did most of the damage, holding 70+ mph on a 3 percent grade. Sedona to Flagstaff RAN: ~49 mi (Trip A delta) at ~0.93 mi/kWh towing (~53 kWh, ~57 min via AZ-179 S back to I-17 and then I-17 N over the rim into Flagstaff). Trip B was reset partway into the leg so it only captured 30.7 mi / 33 kWh of the climb; we used the Trip A delta to back-fill the missed miles. 4,034 ft Sedona to 6,890 ft Flagstaff with a 6,991 ft peak; the steep section is the first 7 mi of AZ-179 S climbing 1,800 ft back to I-17, then I-17 grades into Flagstaff at the cool 7,000 ft plateau. Ambient finally 73°F up in the pines after a day above 80. Sedona RAN ran 116.27 kWh combined across two pedestals (moved stalls to free up parking) over 1h 1m wall-clock, 223 kW peak. Flagstaff RAN: 44.86 kWh in 19m at 212.73 kW peak. Final leg, Flagstaff RAN to Holbrook KOA Journey via I-40 E: 94 mi at 1.21 mi/kWh towing, 78 kWh used, ~1h 41m moving, mostly downhill from 6,890 ft to 5,230 ft. Trip A snapshots: 498.1 mi over 11h 24m at Phoenix Biltmore, 609.2 mi over 13h 24m at Sedona, 658.3 mi over 14h 21m at Flagstaff (~530 kWh), 752.8 mi over 16h 2m at Holbrook the next morning (1.2 mi/kWh, ~627 kWh trip-to-date). Wind 8 mph from the south-southeast off Yuma (KNYL)."

Day 4 ended at American RV Resort in West ABQ after a Gallup → ABQ leg of ~138 mi at 1.32 mi/kWh towing (95 kWh, ~2h 18m moving), elevation 5,200 ft. This morning rolled out at 9:08 AM (tonneau cover packed up on video), Trip A 1,005.6 mi at 1.24 mi/kWh, 806 kWh, elevation 5,715 ft on the West Mesa. Stopped at Hotel Albuquerque parking in Old Town (9:29 AM), the Jesse Pinkman house at 322 16th St SW (9:37 AM), a vintage Route 66 Airstream art piece near Mountain Rd NW (9:45 AM), and the Walter White house at 3828 Piermont Dr NE (10:11 AM, shot from across the street through the wrought-iron security fence the owners installed). I-40 west back to the Uptown RAN at 10:28 AM. Round 1 charge: 48m 40s, 39.64 kWh at 116.96 kW peak, $17.05 gross / $0 net via referral (Order #278297583). Lunch at Twisters / Los Pollos Hermanos (4257 Isleta Blvd SW, 11:55 AM). Round 2 charge at the same pedestal: 12:39 PM, 24.77 kWh in 29m 38s at 100.75 kW peak, $10.65 gross / $0 net via referral (Order #2712825133). The great segment, ABQ Uptown RAN → Tucumcari IONNA: 176.1 mi at 1.66 mi/kWh towing (106 kWh used), the best non-descent leg of the trip. Climbed twice across the leg, first through Tijeras Pass east of ABQ (~6,500 ft), then up to the Clines Corners summit at 7,085 ft (a new trip-record peak elevation), before the long downhill run via Moriarty → Santa Rosa (4,600 ft) → Tucumcari (4,051 ft). Strong SW tailwind of 25 mph gusting 33 mph at KTCC drove the great efficiency on the I-40 east diagonal, and net 3,034 ft of descent (with regen) padded it further. Quick photo stop at the Blue Hole (3:40 PM, 81 ft deep, 61°F water, 3,000-gpm artesian outflow) and at the giant adobe Route 66 Monument in Tucumcari (5:03 PM). IONNA Tucumcari arrival at 5:10 PM, Trip A 1,232.7 mi at 1.30 mi/kWh, 949 kWh trip-to-date, battery 100°F, ambient 90°F. 82.00 kWh charged in 30m 30s at a 220 kW peak (440 V × 500 A), 161 kW average, $34.58 paid (Visa, $0.39/kWh + $2.60 tax, Order #2701434146). First non-Tesla paid charge of the trip; Tesla Supercharger sessions on Days 2-3 totaled $50.17, all eight RAN sessions stayed $0 net via referral. After unplugging Tucumcari, the Tucumcari → Amarillo evening leg ran 119.1 mi at 1.45 mi/kWh towing (82 kWh, ~2h 17m moving), crossing into Central time and the Texas Panhandle. Quick sunset stop at Cadillac Ranch on the I-40 frontage road west of Amarillo (~7:47 PM CDT, the buried Cadillacs in golden hour), then into the Amarillo KOA Holiday around 8:35 PM. The trailer ran on 50A, but the park does not allow EV charging (told at check-in, the moment we pulled in, not to plug the truck in), so the Rivian stayed unplugged and charges the next morning at the Buc-ee's Tesla SC rather than overnight here. Day 5 full-day totals: 346 mi, 225 kWh, 1.54 mi/kWh weighted across the whole day (the morning ABQ loop dragged the trip average down from the 1.66 mi/kWh great segment)."

      "notes": "Day 6 mid-afternoon, at the west-OKC Rivian Adventure Network. Started at the Amarillo KOA (3,588 ft, 51°F) at 8:12 AM after a 119.1 mi / 82 kWh / 1.45 mi/kWh Tucumcari → Amarillo leg the night before. Quick 5-mi run to the Buc-ee's Amarillo Tesla SC at exit 75 for the first paid Tesla charge since Day 3 (85.84 kWh in 58 min, $30.04 on a 325 kW DC stall at $0.32/kWh + 8.25 percent Texas tax). The store inside is its own attraction. Rolled east on I-40 at 10:00 AM with a full pack; crossed into Oklahoma early afternoon. Quick photo + visitor-center swing at the U-Drop Inn in Shamrock TX (12:41 PM), the 1936 Art Deco Conoco that Pixar modeled Ramone's House of Body Art on. Pushed east into the Erick OK Electrify America station at 1:21 PM (Buc-ee's → Erick: 116 mi at 1.15 mi/kWh, 100 kWh, Panhandle headwind hurt the efficiency). EA was the worst charging experience of the trip by a wide margin: the pedestal stencil promised \"UP TO 350 kW,\" reality was an 80 kW average; the session burned 1h 13m to deliver 97.28 kWh and billed $59.79 ($0.56/kWh + 8 percent tax, net $0.61/kWh). Three hours later the west-OKC Rivian Adventure Network put 94.3 kWh into the same pack in 33 min at a 213.18 kW peak, listed at $0.47/kWh, then refunded the whole thing as \"Complimentary charging\" via the referral perk. EA was 2.2x slower per kWh, peaked at under a third of the RAN rate, and charged 1.3x the Rivian-network list price for the privilege. Rivian Adventure Network, Tesla Supercharger, and IONNA Rechargery have each delivered exactly what they advertised at the prices they advertised; Electrify America has not. We took the EA stop because the I-40 gap from Buc-ee's to the OKC RAN is too long for the rig to skip a midpoint, and EA was the only viable non-Tesla pedestal between them. There was no plan B, which is the whole problem with EA being the western-Oklahoma midpoint. Eastbound again at 2:34 PM through Sayre, Elk City, Weatherford, Clinton, El Reno; coasted into the OKC RAN at 5:24 PM at 2 percent SoC / 7 mi of range, the closest we have cut it. Erick → OKC RAN segment: 136.7 mi at 1.20 mi/kWh towing (114 kWh used), derived from cumulative Trip B (252.7 mi / 214 kWh) minus the Buc-ee's leg. Rockwell RV Resort OKC ahead for the night; Pops 66 + Tulsa moved to Day 7."

Final Trip B at the Mingo arrival (3:48 PM CDT): 132.6 mi at 1.23 mi/kWh, 107 kWh used (Trip B reset at the Rockwell gate at departure, so this is the clean full-day figure). Left Rockwell at 10:17 AM at 100 percent SoC. Conditions: 55°F overcast OKC morning warming to ~70°F at Tulsa, light NE wind 6 to 10 mph per KOKC + KTUL observations (a quartering headwind on the eastbound run that held efficiency near 1.23 with the rolling Route 66 terrain). Net descent from Rockwell (1,211 ft) over the Arcadia high point (~1,250 ft) down to Tulsa (608 ft), the lowest the rig has been since the California desert. Stops in order: Pops 66 Soda Ranch in Arcadia (10:53 AM, the 66-foot bottle + 700-soda wall + a four-pack haul), the Arcadia Route 66 Centennial sign + Chicken Shack lunch (11:35 to ~12:30 PM, Mission posed at the sign), a Route 66 art totem near Luther/Wellston, the \"Welcome to Davenport\" Route 66 mural, the Stroud Route 66 neon (est. 1892), and the Heart of Route 66 Auto Museum giant gas pump + OKLAHOMA 66 mural in Sapulpa. Pulled into Mingo around 3:10 PM, set up the Airstream, plugged into 50A FHU. Truck-only run to Tulsa International (TUL) this evening to pick up Diana (lands 6:45 PM); the trailer stays on site.

Trip A closed at Indian Point at 1,946.1 mi (1,946.1 - 1,745.3 leaving Mingo = 200.8). Two clean legs, Mingo to the Lowell AR Supercharger, 111.6 mi at 1.15 mi/kWh (96 kWh), run in the rain into a stiff E/SE wind (KXNA + KTUL averaged ~20 mph, gusting to 33-41), then Lowell to Indian Point, 89.3 mi at 1.30 mi/kWh (68 kWh) once the rain cleared and the road tipped down toward the lake. Rainy 62°F start out of Mingo (overnight L2 there had added 103.9 kWh, unplugged 7:08 AM at 87 percent); the rig read ~90°F parked in the afternoon sun at camp, though official Branson air topped near 75°F. The day's only DC fast charge was Lowell (10:25 AM, 87.82 kWh in 33 min, $36.88) with a BrightDrop electric van on the next stall. Morning stops: Route 66 Rising (7:12 AM), the Blue Whale of Catoosa in the rain (7:30 AM), Hometown Coffee in the old Locust Grove City Drug Store (8:30 AM), then the Missouri state line (~11:47 AM).

The around-town Trip B, running since the reset at the Lowell AR charge the day before, read 113.2 mi at 1.36 mi/kWh (83 kWh), 33 mph moving average over 3 hr 26 min by the evening of May 22. The 24-mile figure is this day's own around-town driving; per-day energy and efficiency are estimates, since Trip B ran un-reset across the Branson basecamp."

First leg to the Springfield Supercharger: 43.2 mi at 1.14 mi/kWh towing into a stiff E wind (KSGF + KSTL ran 22 to 29 mph gusting 37 to 46, 70 to 79°F). Trip A trip-to-date 2,112.4 mi. Second leg to St. Robert (Fort Leonard Wood), 79.6 mi towing, with lunch at Culver's (a double bacon cheeseburger to share) and a big 101 kWh top-off ($38.47); Trip A 2,192.0 there. A third stop at the Wally's IONNA in Fenton (the first IONNA charge of the trip, 84.5 kWh for $18.28 on a Memorial Day $0.20/kWh promo), where the St. Robert leg landed at a brutal 1.04 mi/kWh, 113.8 mi on 109 kWh towing into the headwind; Trip A 2,305.8 there. From Fenton it was a short last run around St. Louis and across the Mississippi into Illinois, about 30 mi more to family's farm in rural Illinois, call it ~265 mi of towing on the day. The whole drive fought a 25 mph ESE quartering headwind, which is why the towing numbers sat in the 1.0 to 1.1 mi/kWh range all day (43.2 mi at 1.14 to Springfield, 79.6 mi to St. Robert, then the worst of it: 113.8 mi at 1.04, 109 kWh, into the teeth of it to Fenton). We boondocked in a quiet field with a stocked pond, s'mores by the Airstream with the Solo Stove fire pit and a long sunset over the water. We did not grab the arrival dashboard, so the precise day-end Trip A stays open."

Free RAN top-up to start, back at the Normal charger on Rivian Motorway in Rivian's own backyard by the plant (37.9 kWh, list $17.06 complimentary). North past distant roadside smoke from a field burn. Pulled into the Rochelle IL Tesla Supercharger around 1 PM for a mid-route top-off: the Rivian membership-pricing handshake refused to start the session (the recurring third-party-host bug, both OEM and A2Z adapters), so we gave up there and pushed on. Up in the Spring Grove area near Fox Lake around 4 PM, Mission started losing function in his back legs and we rushed him to a local vet; x-rays showed a couple of vertebrae pressing on nerves in his back. Steroids and pain meds, a little better but not great, worried about our buddy. One more try at the Spring Grove IL Supercharger just south of Fox Lake (4:59 PM): same membership-pricing fail, red port, but plug-and-charge worked this time at full Tesla pay rate, 34.65 kWh in 11 min for $19.75 at $0.57/kWh. Trip A closed at 2,726.3 by the Fox Lake arrival, 186.1 mi for the day. Dinner was Italian beef at Orlando's, one of our favorite restaurants up here, with Paul Bunyan ice cream at Diana's Ice Cream Shop to close the night.

Trip A read 2,806.8 mi at Rockford (1.26 mi/kWh cumulative, 2,231 kWh trip-to-date).

Right next door, both rigs got their first proper clean since the Cherry Valley detail at Hub City Car Wash, the truck through on Car Wash mode and the Airstream into the tall Super Bay. West across the Illinois plains and down through the Quad Cities (passing a big John Deere facade on I-80), then the day's set-piece: the Iowa 80 Truckstop at Walcott, the World's Largest, where we ran the big midday towing charge (134.3177 kWh in 1h27m for $47.01 at $0.35/kWh) and toured the free Trucking Museum while the pack filled. Then past an OVERSIZE-LOAD house on a flatbed and south off the I-80 corridor to a late-afternoon charge at Mount Pleasant in southeast Iowa (1700 E Washington St, 4:45 PM): 93.3675 kWh in 1h23m for $32.67 at $0.35/kWh, Trip A reading 3,544.4 mi (294.4 mi for the day, 1.32 mi/kWh cumulative). Then south on US-61 across the line into Missouri in the evening light, the rig routed toward a Rivian Adventure Network charger and, beyond it, west on I-70 for a Denver concert with friends. Towing again, and the efficiency drops right back to the towing math: 1.17 mi/kWh for the day where the untethered days ran 2-plus. Warm in Iowa by mid-afternoon, mid-80s with a 10-to-13 mph north crosswind. The day did not stop at Mount Pleasant: it ran on through small-town Paris at dusk to a Columbia RAN charge (108.01 kWh free), then a late I-70 push west to a sleep-at-charger night at the Independence RAN near Kansas City (130.14 kWh, the session erroring at 91 percent after ~53 minutes, finished with a 12.57 kWh top-off in the morning). 582 miles, all on free Rivian charging across Missouri, and the Mount Pleasant to Columbia leg, 176.5 mi at 1.44 mi/kWh, was the longest single tow run of the whole trip."

      "notes": "A truck-only day up into Rocky Mountain National Park from the Lyons basecamp, no towing. We landed both timed entries: the Bear Lake Road corridor in the morning (Sprague Lake, then Bear Lake at 9,450 ft) and Trail Ridge Road in the afternoon (Forest Canyon, the Rock Cut, Alpine Visitor Center at 11,796 ft). Topped out at 12,209 ft on Trail Ridge, the highest point of the whole trip, snowbanks still on the tundra in June. Dashboard readings through the day: into the park at 8,719 ft (79 F ambient, battery 91 F, tires 48 front and 53 to 54 rear), the Bear Lake corridor at 9,696 ft and 80 F, and the high point at 12,209 ft (64 F, battery 95 F, motor temps 138 to 147 F, tires 47 to 53 psi). About 24 mph average on the switchbacks across roughly 113 mi of truck-only park loop. Elk on the road up top, marmots in the rocks, and Mission rode the alpine loop from his cab hammock. Back to the St. Vrain river camp at night, charging free overnight on the campground hookup to leave full in the morning."
