Spring into Action: The Essential RV Pre-Season Checklist

After winter hibernation, your RV needs thorough attention before hitting the road for spring adventures. This comprehensive checklist will ensure your home-on-wheels is ready for the upcoming travel season.

De-Winterizing Your RV Plumbing System

Start by flushing your freshwater system to remove antifreeze residue. Connect to a clean water source, open all faucets, and run water until it flows clear without the pink winterizing solution. Don’t forget to sanitize the system with a bleach solution (¼ cup bleach per 15 gallons of water), letting it sit for 12 hours before flushing thoroughly. Finally, check for leaks at connection points and replace any damaged water filters.

Checking Exterior Seals and Caulking

Inspect all exterior seals, focusing on roof seams, windows, doors, and any roof penetrations. Look for cracking, peeling, or gaps in the caulking that could allow water infiltration. Pay special attention to areas around vents, antennas, and air conditioners where leaks commonly develop. Address any compromised seals immediately with appropriate sealant designed specifically for RVs to prevent costly water damage during spring rains.

Battery Maintenance and Testing

Remove any corrosion from battery terminals using a baking soda solution and wire brush. Check the electrolyte levels in non-sealed batteries and top off with distilled water if necessary. Test battery voltage with a multimeter – a fully charged 12V battery should read 12.6-12.8 volts. Consider a full recharge if readings fall below 12.4V. For optimal performance, have your batteries load-tested at an auto parts store to confirm they’ll handle the demands of your travels.

Tire Inspection and Inflation

Examine all tires for signs of cracking, bulging, or uneven wear patterns. Check the manufacture date – RV tires should typically be replaced every 5-7 years regardless of tread depth due to UV degradation. Inflate tires to the recommended PSI listed on the sidewall or your RV’s specifications while cold. Don’t forget to inspect your spare tire and ensure your tire changing tools are accessible and functional.

Summer Travel Ready: The Comprehensive Mid-Season Maintenance Plan

Mid-season maintenance is crucial for keeping your RV running smoothly during the peak travel months. These timely checks ensure your summer adventures continue without unexpected breakdowns or safety concerns.
