Every Trip Pre-Trip Safety Inspection

▼

Walk-around inspection: all exterior lights functioning (running, brake, turn signals), reflectors secure, license plate visible
Check for fluid leaks underneath RV (transmission, coolant, oil, LP gas)
Tire inspection: tread depth ≥4/32", sidewalls free of cracks/bulges, valve stem caps tight 🛒 Shop TPMS

Set tire pressure to placard specs when COLD; verify TPMS readings log PSI

Pro Tip: Tire Pressure

Always check tire pressure when cold (before driving or 3+ hours after). Temperature affects pressure - for every 10°F change, tire pressure changes by 1-2 PSI. TPMS systems alert you to pressure loss during travel.

Lug nut torque verification using calibrated torque wrench (spec varies by wheel) log torque
Brake system test at low speed; ensure trailer brake controller gain properly adjusted (if towing)
LP gas system check: sniff test around connections, cylinders upright & secured, caps/valve covers in place 🛒 LP Detector

Slide-outs: clear of obstructions, seals intact, slide toppers free of debris and water, awnings properly locked
Interior secure: cabinet latches closed, refrigerator in travel mode/locked, glass covers secured, water pump off, loose items stowed
Battery state of charge ≥75%, spare tire properly inflated to spec, jack & wheel chocks on board
Fire extinguishers charged (pin in place, gauge in green), entry steps retracted, stabilizer jacks fully raised, all doors & compartments locked

Monthly Monthly Maintenance Routine

▼

Safety & Electrical Systems

Test all detectors: smoke, carbon monoxide (CO), and LP gas; replace batteries if >6 months old 🛒 Detectors

Test GFCI outlets (kitchen, bathroom) using test button; verify protected outlets trip correctly
Check converter/charger output: float voltage should be 13.2-13.6V DC; test for parasitic battery draws

HVAC & Climate Control

Clean A/C filter returns and vacuum condenser fins gently (avoid bending fins) 🛒 Filters

Energy Efficiency Tip

Cleaning your A/C filters monthly can improve efficiency by 5-15%, reducing power consumption and extending compressor life. Consider upgrading to a high-efficiency unit if yours is >10 years old.

Run refrigerator on both 120V AC and LP gas mode; LP burner flame should be steady blue (yellow indicates incomplete combustion)
Check furnace operation; replace or clean furnace filter if equipped

Power Systems & Generator

Exercise generator for 30-60 minutes under ≥50% load (run A/C or water heater) log hours

Generator Warning

Never run generator without adequate load - this causes "wet stacking" (carbon buildup) which shortens generator life. Always maintain 50%+ load during exercise runs.

Flooded lead-acid batteries: check electrolyte level (should cover plates); top off with distilled water only 🛒 Battery Monitor

Solar system check (if equipped): verify charge controller operation, clean panels, check connections

Seasonal Seasonal Maintenance (Every 3-6 Months or 5k Miles)

▼

De-winterize plumbing system and pressure test; inspect all PEX connections and tees for leaks at 40-50 PSI
Water heater flush and descale; replace anode rod if ≥50% consumed (Suburban models with anode; Atwood models are aluminum tank) 🛒 Anode Rods

Water Heater Maintenance

A sacrificial anode rod protects your water heater tank from corrosion. Check it every 6 months - if >50% dissolved, replace it. Tanks without anodes (Atwood aluminum) don't require this service. Flushing removes sediment that reduces heating efficiency.

LP gas system leak-down test using manometer; inspect all pigtails, hoses, and regulator; replace any brittle or cracked hoses
Wheel bearing repack (trailers): every 12 months or 12,000 miles; inspect seals, bearings, races for wear log date/miles
Brake system inspection: shoes/pads thickness, brake magnets (electric brakes), rotors/drums for scoring, star wheel adjustment
Roof comprehensive inspection: clean entire surface, check all sealant joints, reseal cracks/voids with compatible sealant 🛒 Sealants

Holding tanks deep clean: use enzymatic tank treatment, clean sensors, verify vent caps intact and clear 🛒 Tank Products

Awning fabric inspection: clean, check tension, lubricate arms, verify lock mechanisms function properly
Slide-out system: lubricate rails/tracks, inspect seals for wear, test emergency manual override, treat seals with conditioner

Annual Annual Deep-Dive & Storage Preparation

▼

Comprehensive fastener audit: roof racks, ladder mounting, awning brackets, slide motor mounts, stabilizer jacks
Battery load test using professional tester; clean terminals with wire brush; apply terminal protectant
Infrared scan of electrical panel under load to detect hot spots (professional service recommended)
LP gas regulator age verification; replace at ~10 years or if showing pressure instability
Detailed cleaning: all roof vents, refrigerator flue, water pump inlet strainer, furnace intake/exhaust
Slide-out seal treatment with appropriate conditioner to prevent drying and cracking
Winterization/storage preparation: fuel stabilizer in generator, rodent exclusion (steel wool/wire mesh), desiccant packs in interior, breathable RV cover 🛒 Winter Supplies

Emergency equipment check: first aid kit, fire extinguishers (5-year inspection due), roadside triangle reflectors, flashlights
Appliance maintenance: refrigerator burner tube cleaning, furnace blower lubrication (if applicable), water pump check valve inspection

Every Trip Trailer-Specific Pre-Trip Checklist

▼

Hitch & Coupling System

Coupler latch operates smoothly; ball size matches coupler (2", 2-5/16", etc.); coupler lock engaged; safety pin installed 🛒 Hitches

Weight Distribution Hitches

A weight distribution hitch (WDH) is essential for trailers >3,500 lbs. It redistributes tongue weight to all axles, improving handling, braking, and reducing rear squat. Modern systems like Equal-i-zer integrate sway control for safer towing.

Safety chains crossed properly under coupler; correct length (not dragging); hooks/clips intact and facing up
Breakaway switch and cable tested; pull pin to verify trailer brakes activate independently; replace 12V battery if >3 years old
7-pin connector: all pins clean, grease applied, connection secure; test lights and brakes before moving

Running Gear & Suspension

Leaf springs inspect for cracks; equalizers, shackles, and wet bolts show no excessive wear; all bushings intact; apply lubricant to pivot points
Axle U-bolts torqued to spec (typically 45-70 ft-lbs, verify for your axle); spring hangers not elongated log torque
Frame and cross-member inspection for cracks, especially near welds and stress points

Rear Overhang Protection

Inspect rear stabilizer jacks for signs of prior strike damage or bending from steep driveway encounters 🛒 Protection

Rear bumper and trim attachment secure; verify clearance for departure angle on steep exits

Seasonal Trailer Seasonal Maintenance

▼

Wheel bearing complete repack: remove, clean, inspect races and bearings for pitting, repack with marine-grade grease, install new seals log date/miles

Critical: Bearing Maintenance

Wheel bearing failure is a leading cause of trailer accidents. Repack every 12 months or 12,000 miles regardless of use. Check for heat after first 10 miles of travel - hubs should be warm but touchable.

Verify no grease on inside rim surface (indicates over-packing or seal failure)
Electric brake magnets: check wear (should have ≥1/8" material remaining), verify wiring protection through drop arm, star wheel adjustment for proper drag
Brake controller calibration: adjust gain setting for proper trailer braking without lockup
Stabilizer jacks: extend/retract smoothly without binding; screws not bent; feet intact and secure
Tongue jack: grease gears, inspect weld mounts, verify wheel rotates freely
Propane tank tray and hold-down: check for rust/corrosion, ensure mounting bolts tight, test auto shut-off valve

Every Trip Motorhome Pre-Trip Inspection

▼

Engine & Chassis

Check all fluid levels: engine oil (dipstick), coolant (cold check at reservoir), power steering, brake fluid; look for fresh leaks underneath
Parking brake holds vehicle on incline; ABS warning light self-test completes normally (goes off after start)
Tire pressure set to load-adjusted specifications (weigh each axle to determine proper PSI) 🛒 TPMS

Engine start check: no unusual noises, smooth idle, all gauges (oil pressure, temperature) in normal range within 30 seconds
Air brake system (if equipped): build pressure to cutoff (typically 120-135 PSI), test governor cutout, check for air leaks at connections

Towed Vehicle (If Flat-Towing)

Base plate attachment bolts torqued; tow bar properly secured; safety cables crossed and connected 🛒 Tow Equipment

Supplemental braking system armed and tested (required in most states)
Towed vehicle lighting: verify all lights function via adapter or wireless system

Seasonal Motorhome Seasonal Maintenance

▼

Engine oil and filter change per manufacturer miles/hours schedule (typically 5k-7.5k miles or 6 months) log date/miles
Chassis lubrication: grease all fittings (steering linkage, suspension, driveline), inspect boots for tears
Drive belts inspection: check for cracks, fraying, proper tension; replace if >5 years or showing wear
Air filter replacement (engine and cabin); inspect PCV valve operation
Cooling system: pressure test entire system including radiator cap; inspect hoses for soft spots/cracks; flush/refill per OEM schedule (typically 30k-50k miles or 3-5 years)
Transmission service per OEM interval (fluid/filter change typically 30k-50k miles); scan for stored codes

Transmission Care for Motorhomes

Transmission is the most expensive component to replace (~$4,000-8,000). Follow OEM service intervals religiously. Consider adding an auxiliary transmission cooler if towing or driving in mountains frequently. Check fluid color monthly - dark brown or burnt smell indicates overheating.

Weigh vehicle at certified scale: gross vehicle weight and individual axle weights; adjust tire pressure based on actual loads, not placards log weights
Tire date code verification: replace if ≥7 years old regardless of tread depth (use DOT date code on sidewall)
Steering system: check for play in steering wheel (should be <2" free play), inspect tie rod ends, drag link, center link for looseness
Brake system: pad/shoe thickness measurement, rotor/drum condition, brake fluid color (should be light amber, not dark), brake line inspection for corrosion
Diesel systems (if applicable): fuel filter replacement, water separator drain, DEF fluid level check (if equipped with SCR)
Chassis battery maintenance: load test both house and chassis batteries; clean terminals; check mounting brackets
