RV travel in Arizona
Arizona is one of the most rewarding RV states in the country. The Grand Canyon, Sedona, Saguaro, Petrified Forest, and Monument Valley are all within a long week's loop. The roads are big and well-maintained, fuel is plentiful, and the BLM around Quartzsite is one of the largest free-camping areas in North America. The catch is the climate: the Sonoran Desert in July is genuinely dangerous for any rig without serious airflow, and the monsoon thunderstorms from late June through September can flood low washes within minutes. Plan around it and Arizona is one of the best states to spend a fortnight in.

RV-friendly and RV-restricted highways
RV-friendly
I-10Coast-to-coast main corridor through Phoenix and Tucson. Big rigs, easy.
I-40Old Route 66 corridor across the north. Flagstaff at 7,000 ft gets snow Nov-Mar; chains may be required.
I-17Phoenix to Flagstaff. Steep 6% grades on the climb out of the Verde Valley. Use lower gears descending.
I-8Yuma to Casa Grande. Empty desert; long fuel gaps between exits. Carry water.
US-89/US-89AScenic alternative through Sedona, Oak Creek Canyon, and up to the Grand Canyon. Tight switchbacks south of Flagstaff -- not recommended for rigs over 35 ft.
US-191Eastern Arizona via Greer and the White Mountains. High elevation, scenic, slow. Closed sections in winter.
RV-restricted
AZ-87 north of Payson (Mogollon Rim)Steep grades and tight curves. Rigs over 40 ft are technically permitted but practically a bad idea.
AZ-261/AZ-273 (Sunrise Park)Seasonal closures Nov-May. Not for fifth wheels.
Bright Angel/South Kaibab Trail (Grand Canyon)Hiking trails. RVs prohibited (obvious, but worth saying).
National parks and monuments
Grand Canyon NP (South Rim)$35/vehicle (7 days), $80 America the Beautiful annual. Mather Campground requires reservation Mar-Nov via recreation.gov; book 6 months ahead. Trailer Village takes hookup-needs RVs up to 50 ft.
Grand Canyon NP (North Rim)$35/vehicle (7 days). Open mid-May to mid-Oct only. North Rim Campground reservable via recreation.gov.
Petrified Forest NP$25/vehicle (7 days). No camping inside the park. Backcountry permits available; nearest RV camping in Holbrook.
Saguaro NP (East + West)$25/vehicle (7 days). No RV camping in either district. Stay in Tucson or at Catalina State Park.
Canyon de Chelly NMFree entry (Navajo Nation tribal park). Cottonwood Campground first-come; small rigs only. Navajo guide required for canyon floor.
Glen Canyon NRA (Lake Powell)$30/vehicle (7 days). Wahweap Campground reservable; Lone Rock Beach is dry-camp on the sand (4WD recommended for soft spots).
Organ Pipe Cactus NM$25/vehicle (7 days). Twin Peaks Campground first-come Nov-Mar peak season; RVs to 35 ft. Mexican border 5 miles south -- check current advisories.
Chiricahua NMFree entry. Bonita Canyon Campground reservable Mar-May; RVs to 29 ft. Steep narrow access road -- not for big rigs.
Wupatki/Sunset Crater NM$25/vehicle (7 days, combined). No camping in either monument. Bonito Campground (USFS) adjacent to Sunset Crater takes RVs to 40 ft.
Boondocking and dispersed camping
BLM: Arizona has some of the best BLM dispersed camping in the country. The big two: Quartzsite (La Posa Long-Term Visitor Area, $40 for 14 days, $180 for the season Sep-Apr; outside the LTVA boundary it's free 14-day dispersed) and the Sonoran Desert National Monument south of Buckeye. Most BLM in Arizona allows free 14-day dispersed camping unless posted otherwise.
National Forests: Coconino, Kaibab, Tonto, and Apache-Sitgreaves National Forests all permit free dispersed camping along forest roads. Coconino's roads around Flagstaff (FR 552, FR 545) are popular. Fire restrictions are common Apr-Oct -- check current status before you light anything.
Stay limit: typically 14 days per location.
Service stops
Propane: Plentiful in Phoenix, Tucson, Flagstaff, and along I-10 and I-40. Sparse in the eastern White Mountains and along the Mexican border. Most KOA and Good Sam parks fill on-site. U-Haul locations are reliable for refills (not exchanges) and accept most tank types.
Dump stations: Dense in Phoenix, Tucson, and along I-10/I-40. Most state parks have free dump stations for registered guests. Flying J / Pilot truck stops along the interstates have fee dump stations ($10-15). Quartzsite has multiple commercial dump stations open year-round.
Fuel: Diesel and gas widely available along all interstates and US highways. Arizona has unusually long stretches between fuel stops on US-191 (Springerville to Alpine, 30 miles), AZ-89A through Oak Creek Canyon, and the Apache Trail (now closed past Tortilla Flat anyway). Carry an extra 5 gallons if you're heading off-interstate in eastern Arizona. Fuel prices typically lowest in Tucson, highest in Sedona and the Grand Canyon area.
Weather windows
Best monthsLate October through April. Daytime highs in the desert sit in the 60s-80s F; nights drop to 30s-50s F.
Avoid monthsJune through early September. Phoenix routinely hits 110-118 F. RV interiors without solar-vent fans become unsafe within 30 minutes of parking. Flagstaff and the Mogollon Rim stay 20-30 F cooler but get violent monsoon storms with flash-flood risk in any low wash from late June onward.
Never park in or cross a low wash during a monsoon storm. Walls of water 6-8 ft high travel down dry washes within minutes of a thunderstorm 20 miles upstream. "Turn Around Don't Drown" is not an exaggeration.
