RV and Vehicle Dwelling Preparedness

The RV Preparedness Profile

Full-time RV and vehicle dwellers operate under a unique set of constraints and advantages. Understanding both determines what effective preparedness looks like for mobile living.

The mobility advantage: An RV can be 200 miles from a disaster zone in 4 hours. A house cannot be. This is genuine and significant.

The storage constraint: A 40-foot Class A motorhome has roughly the storage of a small studio apartment. A converted van has a small closet's worth. Supply depth is fundamentally limited compared to a fixed property.

The infrastructure dependency: RV living depends on external water fills, dump stations, and either shore power or generator/solar for electrical. Unlike a home with a well, an RV can't operate indefinitely without external service points.

Water Systems for RV Dwellers

Standard RV freshwater tanks: Range from 20 gallons (smaller rigs) to 100 gallons (large Class A). At 2 gallons per person per day for minimal use, a 50-gallon tank is 25 days for one person — but only if you're conserving aggressively.

Water conservation practices:

• Dishwashing in a basin (not running tap) saves 3-5 gallons per session
• Navy showers (wet, turn off, soap, rinse) use 2-3 gallons vs. 10+ for running showers
• Bottled water for drinking from a water delivery schedule
• Grey water goes to grey tank; black water goes to black tank — know the difference in your rig

Emergency water backup: A 5-7 gallon portable container (WaterBrick, NATO jerry can) stored in an external compartment provides buffer when the main tank is getting low and you're between water fills.

Water fill network: Know where you can fill fresh water in the areas you travel. National parks, truck stops (many have RV dump and fill stations), Flying J/Pilot travel centers, and campgrounds are all fill points. In an emergency, identify fire hydrant systems that allow emergency water access (some municipalities have this, requires permits in normal times).

Power Systems

The baseline: Most RV living requires either shore power, generator, or solar + battery. In an emergency, shore power is unavailable; the question is how long you can sustain on your own power.

Generator: Most RVs have a built-in generator (propane or diesel). Know its fuel consumption rate. At 10-15 hours per day running the A/C in summer, a 30-gallon diesel generator tank lasts 4-6 days. Plan accordingly.

Solar + lithium battery: The most sustainable off-grid RV power. A 400-800W solar array with 200-400Ah lithium battery handles most RV loads indefinitely in adequate sun (running fans, refrigerator, lights, devices). Running air conditioning requires 1,000+ watts of solar and large battery capacity — achievable but expensive.

Lithium vs. lead-acid: Lithium batteries (LiFePO4) in RV applications are worth the premium cost: they provide 80-100% usable capacity vs. 50% for lead-acid, last 3-4x longer in cycles, and weigh much less. The cost difference is real ($800-1,500 for a 100Ah lithium vs. $150 for comparable lead-acid) but the performance difference is significant for full-time living.

Food Storage in an RV

The space constraint is real. Creative solutions:

Dead space in cabinet and compartment corners: External storage bays are often underutilized, especially for water-resistant, non-food items that can be stored externally (freeing interior space for food).

Under-dinette and under-bed storage: Standard RV design includes storage in these spaces; many full-timers reinforce or rebuild these with proper shelving.

Calorie-dense, space-efficient foods: Same principle as urban apartment — rice, beans, pasta, nut butters maximize calorie-per-cubic-inch.

Realistic supply window: 30 days of food in a well-organized RV is achievable with dedicated storage. 90 days is impractical for most rigs. The compensating factor is mobility: unlike a hunkered-down homeowner, an RV dweller can drive toward resupply.

Vehicle Reliability as Preparedness

Your RV or vehicle is both your home and your bug-out vehicle. Mechanical reliability is preparedness.

Maintenance schedule compliance: The most critical RV preparedness action. Deferred maintenance becomes a breakdown at the worst possible time.

Emergency supply in the rig:

• Full spare tire in working condition (inflation checked monthly)
• Tire inflation system (air compressor or portable inflator)
• Jump-start pack
• Basic tools (socket set, screwdrivers, pliers, fuses)
• Tow rope or recovery strap
• Water for cooling system emergency

Know your rig's common failure points: Every RV model and generation has known issues. Join the model-specific owners forum and know the top 5-10 failure modes for your specific rig. Having the repair parts for common failures prevents long roadside waits.

Security for RV Dwellers

Campground and parking security:

• Research parking spots in advance; know the security history of campgrounds and overnight spots you use
• Keep valuables out of sight in the cab
• Wheel locks for extended parking in unknown areas
• Security camera (battery or 12V powered) covering the door and common entry point

Breakin prevention:

• Deadbolt on the main door in addition to the standard lock
• Security screen door (many RV-specific products available)
• Window security film
• Motion-activated exterior lighting

The appearance principle: A working-class, unremarkable appearing RV is less targeted than a visibly expensive or obviously well-equipped rig. Avoid exterior accessories that signal high-value electronics or equipment.

The Network of Destinations

The RV dweller's equivalent of a bug-out location is a network of known safe destinations:

Trusted contacts in different regions: Family, friends, or fellow RV community members who can host for an extended period if needed. Established in advance.

Campground memberships: Thousand Trails, Encore, KOA Value Kard — annual memberships that provide access to campgrounds with established infrastructure. In an emergency, a paid campground with power and water is significantly better than dispersed camping without.

Federal lands dispersed camping: National Forest and BLM lands allow free dispersed camping (usually up to 14 days in one spot). In many regions, there is more than enough space for every RV in the country. A GPS-capable device loaded with offline maps identifying BLM and National Forest boundaries is a valuable resource.
