Mastering Seasonal Maintenance

Whether you are facing an early freeze warning or preparing for long-term storage, winterization is non-negotiable. Many owners debate if a complete system flush is necessary, but skipping the water lines is a risk that often leads to cracked pipes and expensive plumbing repairs.

The Pink Stuff: How Much Do You Need?

For most travel trailers and mid-sized motorhomes, three to four gallons of RV-specific antifreeze is usually sufficient to protect your water heater bypass, kitchen sink, bathroom vanity, and shower. Always ensure your hot water tank is bypassed before pumping the fluid, as you do not want to fill your tank with antifreeze.

Tires, Leveling, and Structural Integrity

Proper storage goes beyond just locking the door. Tires are sensitive to long-term pressure; avoid parking on bare ground, which can cause moisture wicking and rot. If you are using leveling blocks, ensure they are placed properly—we have all seen the "creative" but incorrect uses of Anderson levelers that compromise stability.

Optimizing Your Internal Space

Many owners ask if removing drawers from under-bed storage is worth the effort to increase access. While it adds depth for seasonal gear, ensure you are not compromising the structural integrity of the bed base. If you're designing custom storage buildings, prioritize climate control and ventilation to prevent mold during humid months.

Storage Facility Best Practices

Choosing between covered storage and open-air parking depends on your local climate and budget. Covered storage is highly recommended to protect your roof seals from UV damage and prevent snow pile-up. Always check your site for proper drainage so you aren't parked in a puddle.
