Free camping saves $30-60/night vs. commercial parks.

Mojave Desert Summer Safety

Yes, however summer travel in the Mojave Desert (June to September) requires preparation for temperatures of 110 to 120°F.

Extreme Heat Hazards:

Tire Blowouts: Hot pavement increases the risk of failure. Check pressure cold daily. Carry a tire gauge. Ensure manufacturer specifications for RV weight.

Engine Overheating: Watch temperature gauges on grades. If overheating: turn off AC, maximize heat (pulls heat from engine), find a pullout to cool. Carry extra coolant.

AC System Stress: Units work continuously. Generator fuel consumption increases. Some struggle above 110°F. Drive during cooler hours (5-11 AM).

Dehydration: Drink frequently minimum 1 gallon per person per day. Symptoms: headache, dizziness, dark urine. Avoid alcohol/excess caffeine.

Flash Flood Dangers:

Critical Rule: Never park an RV in a dry wash (sandy creek bed), even if the sky is blue. Flash floods are the #1 weather-related killer. Water arrives with zero warning from distant storms. Choose elevated camping away from drainage channels. Monitor weather.gov before travel.

Limited Services & Communication:

Plan fuel stops (Victorville, Barstow, Baker). Never drop below 1/4 tank. Cell coverage is inconsistent. Download offline maps. Consider a satellite messenger (Garmin inReach).

Summer Strategy: Depart sunrise (5-6 AM), avoid midday travel (noon-5 PM), plan AC breaks, carry 5 gallons of water per person, monitor tire pressure daily, travel with a full tank.

Spring/fall eliminates most hazards, so adjust dates if possible.

Best RV Class for LA to Vegas

Class B Campervans - Best for Couples: Superior fuel efficiency (15 to 20 MPG), easy parking, compact (under 22’). Limited storage, less effective AC in extreme heat.

Class C Motorhomes - Best Overall: Family-sized (25 to 32’), moderate fuel efficiency (10 to 14 MPG), robust AC for desert heat, comfortable for 4 to 6 people. Optimal compromise.

Class A Motorhomes - Best for Comfort: Maximum amenities, residential AC, spacious. Lower fuel economy (8 to 10 MPG), challenging parking at attractions.

Frequently Asked Questions About the LA to Vegas RV Road Trip

Do I need to reserve campgrounds along this route in advance?

No, you don’t need to reserve the campground along the LA to Las Vegas route but check what season you are travelling in, as reservations should be made during peak seasons. Advance reservations are typically not required except during major Las Vegas events or holiday weekends. BLM and Mojave Preserve campgrounds are first-come, first-served. Vegas RV parks during conventions, Super Bowl, or NYE book 4-6 weeks ahead. Mid-week/off-season allows same-day bookings.

Is there a fuel strategy for this desert drive?

Yes, the key fuel strategy is to avoid remote areas with expensive fuel. Fuel up in Victorville or Barstow for the best prices. Avoid Baker (remote = expensive). Ensure 3/4 tank before Mojave Preserve (no services inside). Never drop below 1/4 full. Carry 5-10 gallons extra for remote roads.

Can I take scenic detours along Route 66 with my RV?

Yes, there are many scenic detours that you can take along Route 66, but they need to be evaluated. National Trails Highway (Barstow-Amboy) accommodates RVs under 35’ with fair conditions. Original alignments east of Amboy have rough pavement/narrow passages—use I-40 alternative. Plan ~100 miles RV-suitable Route 66 (adds 2-3 hours).

Are there RV dump stations along the LA-to-Vegas route?

Yes, there are several dump stations along the LA-to-Vegas route. Victorville and Barstow have commercial RV service centers. Flying J and Love’s truck stops on I-15 offer dumps ($10-15 fee). Baker has limited services. Vegas has numerous options. Most commercial parks allow non-guests to use the dump for a nominal fee.
