Seasonal Maintenance

Staying on top of maintenance prevents expensive repairs and keeps the camper safe and comfortable. Here’s what to do and when.

---

Before every trip

• Check tire pressure (check the sidewall for max PSI — typically 50–65 PSI for trailer tires)
• Inspect tires for cracks, bulges, or uneven wear
• Check lug nuts — torque to spec (typically 90–120 ft-lbs for trailer wheels)
• Test all lights (brake, turn, running)
• Test trailer brakes
• Check propane levels
• Inspect roof and exterior seals for damage
• Check all exterior compartment latches

---

Every trip (after returning)

• Dump and flush black and gray tanks
• Rinse and dry the sewer hose
• Wipe down the interior — moisture and food attract pests
• Check for any new leaks or damage
• Leave cabinet doors slightly open to prevent mildew

---

Monthly (during camping season)

• Test smoke detector and CO/propane detector (press test button)
• Check fire extinguisher pressure gauge
• Inspect roof for cracks, bubbles, or lifted seams
• Check and clean A/C filter (rinse with water, let dry)
• Inspect awning fabric and arms for damage
• Check battery water level (if flooded lead-acid) and charge level

---

Annually (spring / start of season)

Roof

• Inspect entire roof for cracks, holes, or lifted seams
• Apply lap sealant to any cracks around vents, A/C, and seams
• Clean roof with RV roof cleaner (not petroleum-based products on rubber roofs)

Seals and caulking

• Inspect all exterior seams, windows, and doors for cracked or missing caulk
• Re-caulk with self-leveling lap sealant as needed

Tires

• Check manufacture date (DOT code on sidewall — last 4 digits = week/year)
• Replace tires older than 4–6 years regardless of tread
• Check wheel bearing condition (have a shop inspect if you hear grinding)

Propane system

• Inspect propane hoses for cracks or brittleness — replace every 2–3 years
• Test all propane appliances
• Have the propane system inspected by a qualified service center every 6 months
• Check regulator — replace every 10–15 years

Water system

• Sanitize the fresh water tank (see below)
• Inspect all water lines for cracks or leaks
• Replace water filter cartridges

Electrical

• Check all 12V connections for corrosion
• Test battery capacity — replace if it won’t hold a charge
• Inspect 7-pin connector for corrosion

Fresh water tank sanitization

Do this at the start of each season and if the water tastes or smells off.

1. Mix 1/4 cup of household bleach per 15 gallons of tank capacity.
2. Fill the tank with the bleach solution.
3. Run water through all faucets until you smell bleach.
4. Let sit for 4 hours (or overnight).
5. Drain the tank completely.
6. Refill with fresh water and flush all lines.
7. Repeat the flush until the bleach smell is gone.

Roof sealant (lap sealant)

Check and reapply annually. Use Dicor self-leveling lap sealant for horizontal surfaces and Dicor non-sag for vertical surfaces.

1. Clean the area with rubbing alcohol.
2. Apply sealant generously over any cracks or gaps.
3. Smooth with a wet finger or tool.
4. Allow 24 hours to cure before rain.
