California: The Overlanding Capital of North America

No state in the country offers the diversity of terrain, climate, and landscape that California does for expedition travel. Within a single state, you can go from below-sea-level desert salt flats to 14,000-foot alpine terrain, from Pacific coastal cliffs to volcanic lava fields, from Mojave sand dunes to redwood canopy.

It's no coincidence that RREV builds in California. This terrain — aggressive, varied, demanding — is what our trailers are engineered for.

The Five Expedition Zones of California

The Mojave & Death Valley

The Mojave Desert and Death Valley are California's most demanding expedition environments. Summer temperatures regularly exceed 120°F. Winter nights drop below freezing. The terrain alternates between compressed hardpack, loose sand, rocky washes, and dried lake beds.

What you need: Superior cooling (roof vents, shade management), large water capacity (90+ gallons for extended stays), heat-resistant materials, and a trailer that doesn't become a solar oven when parked.

Best routes: Saline Valley road, Racetrack Playa approach, Surprise Canyon, Mojave Road (National Trails Highway).

Season: October through April. Avoid May–September unless you're specifically prepared for extreme heat.

The Eastern Sierra

The Eastern Sierra — from Lone Pine to Bridgeport — is the most scenically dramatic overland region in North America. The approach roads climb from 4,000 feet to 13,000+ feet in relatively short distances. The terrain is volcanic rock, loose talus, and alpine meadow.

What you need: High clearance (12"+), substantial suspension travel, 4WD capability on your tow vehicle, and four-season insulation — nights are cold even in August at altitude.

Best routes: White Mountains (Ancient Bristlecone access), Horseshoe Meadows road, Cottonwood Lakes approach, Buttermilk Road.

Season: June–October for high routes. Year-round for lower access roads.

The Coast Ranges & Lost Coast

Northern California's coastal ranges — particularly the Lost Coast — are the most underrated overland terrain in the state. Dramatic sea cliffs, old-growth forest, and complete solitude. Roads are narrow, often muddy, and frequently impassable for trailers over 7 feet wide.

What you need: A compact trailer (the RREV Outland Edition is ideal here at 18ft). Good mud tires. Patience with single-lane roads and no cell service.

Best routes: King Range National Conservation Area, Mendocino backroads, Sinkyone Wilderness State Park perimeter roads.

Season: June–October for dry conditions. Spring offers incredible wildflowers but expect mud.

The San Bernardino & San Jacinto Mountains

Southern California's mountain ranges offer accessible off-road terrain within a day's drive of 20 million people. Big Bear, Arrowhead, and the San Jacintos provide everything from maintained forest service roads to technical rocky trails.

Best routes: Holcomb Valley, Big Pine Flat, Cactus Flat, Thomas Mountain Road.

Season: April–November. Snow access in winter requires chains or traction devices.

Baja California — The Classic

Technically Mexico, but the Baja Peninsula is the spiritual home of California overlanding. 1,000 miles of desert, Pacific coast, and Sea of Cortez — with more isolation, more stars, and more adventure than anywhere else accessible from Southern California.

What you need: Satellite communication (Garmin inReach or equivalent), additional fuel capacity (some fuel stretches are 200+ miles), Spanish basics, Mexican insurance, and a rig that can handle deep Baja washboard without coming apart.

Best routes: The Baja Divide, Mike's Sky Ranch approach, Cataviña boulder garden, Laguna Hanson (Constitución de 1857 National Park).

Season: October–April. Summer heat in Baja is severe.

What California Terrain Demands From a Trailer

The RREV lineup was designed by people who run these trails. A few non-negotiables for California expedition use:

  • Clearance: 12" minimum front-to-rear. California's rocky approaches don't forgive low-slung trailers.
  • Width: The Lost Coast and Baja back roads require trailers under 7'6" wide for many sections.
  • Water capacity: Death Valley and remote Baja can go 200+ miles between reliable water sources. Minimum 60 gallons for two people on a 5-day Baja run.
  • Dust management: Mojave and Death Valley dust is extraordinarily fine. Positive pressure cabins or excellent door sealing is essential.
  • Heat management: Southern California summer camping requires shade structures, good ventilation, and ideally refrigeration that doesn't depend on ambient temperature.

Getting Permitted

Most California National Forest and BLM land allows dispersed camping without a permit — typically you can stay 14 days in one location before moving on. Some high-use areas (Alabama Hills, Anza-Borrego) have specific rules and permit requirements during peak season. Always check with the specific ranger district before your trip.

Built Here, For Here

Every RREV trailer is built in California and tested in California terrain before delivery. When you order an RREV, you're getting a rig built by people who know this terrain personally — not imported from the other side of the planet and sold to you by a dealer.

That matters when you're somewhere between Lone Pine and Death Valley Junction with a problem.
