Picking Up Your RV: What to Check Before You Leave
Walk around the entire rig before signing anything. Check tires for wear and pressure. Look at all external storage bay latches — they pop open on highway. Test every slide-out if the rig has them. Ask the rental agent to demonstrate the hookup process, dump procedure, and generator start sequence, and video the walkthrough on your phone. Confirm the propane level, water tank level, and that both gray and black tanks start empty. Note any existing damage on the pre-existing condition form. The most common first-timer mistake: not doing the walkthrough slowly enough and then calling support from a campground at 10 PM.
Driving an RV in Arizona: Height, Width, and Speed
Arizona's primary RV routes are highway-friendly, but a few non-obvious rules apply. Know your rig's height — the rental contract lists it, typically 11–12 feet for a Class C. Some Tucson underpasses and urban areas have clearance issues. Keep a sticky note on the dash: HEIGHT IS [X] FEET. Speed limit for most Class C rigs is 55 MPH on Arizona highways, though most RVers run 60–65 without issue. Budget 20–25% more time than your GPS estimates for any route. Turning radius is longer than you think — overshoot turns by at least one full lane. When backing into a campsite, use a spotter or set up a backup camera before your trip.
Your First Campground Hookup: Electric, Water, Sewer
At a full-hookup site, connect in this order: (1) Electric first — run the cord from the post to the RV, turn off the post breaker, plug in, then turn on the breaker. (2) Water — connect the hose to the post and the RV's water inlet, turn on slowly and check for leaks. Use a drinking-water-safe hose — rental companies should provide one. (3) Sewer last — connect the sewer hose to the RV's dump outlet, then to the ground connection. At a partial-hookup site (electric and water, no sewer), you use your holding tanks and dump at a dump station before leaving. Never leave sewer valves open — run tanks at least 2/3 full before dumping to flush effectively.
Managing Your Tanks: Water, Gray, and Black
Every RV has three tanks: fresh water (what you use), gray water (sink and shower drain), and black water (toilet). In dry camping (no hookups), you live off your fresh tank and fill gray and black over the trip. A Class C typically holds 40–50 gallons fresh, 35–45 gallons gray, 30–40 gallons black. At average use, that's 3–5 days before dumping. Watch your tank gauges — camping with a full black tank is miserable. Dump stations are at most campgrounds and many Flying J / Pilot truck stops. The fee is $10–$20 or free with campground registration.
Arizona-Specific Tips: Heat, Dust, and Altitude
Heat management is the top concern for Arizona RV trips below 4,000 feet from May through September. Run your AC during the hottest hours (1–5 PM) and pre-chill the rig. Shore power (campground electric hookup) is strongly preferred over generator use in heat — generators run hot themselves and can overheat in sustained summer operation. Watch for haboobs — dust storms that can roll in fast in the monsoon season (July–September). Pull off the highway immediately if visibility drops. At high elevations (Flagstaff, Prescott), your generator loses about 3% efficiency per 1,000 feet — expect reduced output. Carry extra water: a minimum of 1 gallon per person per day plus RV supply for Arizona desert camping.
Frequently Asked Questions
Is it hard to drive an RV for the first time?
Most first-time renters are comfortable within an hour of driving. The main adjustments: wider turns, longer stopping distance, and awareness of your height at clearances. Start on open roads before urban areas. Arizona's highways are wide and well-signed. The trickiest part is campground maneuvering — use a spotter and take it slow. Most rental companies include a brief orientation drive.
How long can I go without dumping tanks?
At moderate use (2 adults), expect 4–6 days before the gray tank fills. The black tank typically lasts a day or two longer. Tank capacity varies by rig — ask your rental company. Plan dump stops at campground dump stations or Flying J/Pilot stops (usually $10–$20). If staying at full-hookup sites, sewer connection keeps tanks empty continuously.
Do I need a special license to drive an RV in Arizona?
No. Standard Arizona and out-of-state driver's licenses are valid for motorhomes up to 26,000 lbs GVWR, which covers all Class C and most Class A rentals. Commercial licenses are only required for vehicles over 26,001 lbs — typically rigs above 45 feet that rental companies don't rent to casual renters anyway.
