If replacement is needed, use a socket wrench to unscrew the old rod and install a new one, using Teflon tape on the threads for a good seal. This should be checked and possibly replaced annually, depending on factors like water hardness.

Flushing Out Sediment: Remove any sediment build-up by flushing the tank with clean water after removing the anode rod.


Maintaining the exterior of your RV, particularly when traversing the diverse landscapes of Montana’s Camping Destinations, is crucial for both its longevity and your safety and enjoyment while on the road. This maintenance encompasses various aspects from regular cleaning to protect against the elements, to using the right sealants and coatings to preserve its exterior. By adhering to these practices, you ensure that your RV remains in top condition, whether you’re exploring the scenic routes of Montana or resting in one of its many serene RV parks. Here’s an overview of key exterior maintenance practices for RVs, complete with insights on the best sealants and coatings to use, based on gathered information from reliable sources

Regular Cleaning and Inspection

The cornerstone of exterior RV maintenance is regular cleaning and inspection. This isn’t just about aesthetics; cleaning your RV helps you spot potential issues before they worsen. When washing the exterior, pay particular attention to the roof, as debris and water accumulation can lead to damage over time. Inspect seals, seams, windows, and doors for cracks or leaks. This type of scrutiny helps in early detection of issues which can be rectified before they turn into expensive repairs.

Tire Care and Maintenance

Tires are critical to your RV’s safety and performance. Regular tire maintenance includes checking for proper inflation, examining tread depth, and looking for signs of wear or damage. Tire pressure should be checked before every trip and monthly when the RV is in storage. Remember, tire issues can lead to decreased fuel efficiency and, more importantly, pose significant safety risks.

Sealant and Seam Inspection

Inspecting your RV’s seams and seals starts on the roof. Look for deep cracks or voids in the lap sealant and around roof-mounted accessories like vents, A/C units, solar panels. When resealing is needed, a self-leveling lap sealant is recommended for horizontal surfaces. Dicor and Alpha Systems are two leading brands suggested for the best sealants for RV roof seams. For vertical surfaces, a silicone sealant is ideal due to its less likelihood to drip or ooze down.

Recommended Sealants and Coatings

For general use, including both internal and external applications, 3M Marine Adhesive Sealant 4000 UV is highly recommended. It offers excellent UV resistance and forms a flexible, durable bond suitable for harsh conditions. For roof maintenance, ToughGrade Self-Leveling RV Lap Sealant is suitable for aluminum and metal surfaces, though it may not be ideal for rubber roofs. RecPro 1021 Self-Leveling RV Sealant is another excellent option, especially for EPDM rubber roofs, offering all-weather protection and resistance to chemicals and oils.
