🛠️ Viair RV Maintenance Bundle (400P-RVS or 450P-RVS + Winterization Kit)

Year-Round RV Care Made Simple

Be ready for every season with this all-in-one Viair RV Maintenance Bundle — featuring your choice of the Viair 400P-RVS or 450P-RVS Automatic Tire Inflator, plus the Viair Winterization Kit. Whether you’re topping off your tires before hitting the road or protecting your RV’s water system before the first freeze, this bundle has you covered.

🚐 Why You’ll Love This Bundle

1. All-Season Preparedness
Keep your RV road-ready in summer and protected in winter. This combo ensures your tires stay properly inflated for safe travels and your plumbing stays damage-free during cold storage.

2. Fast, Reliable Tire Inflation
Both the 400P-RVS and 450P-RVS are built specifically for RVers. Each delivers powerful, portable air wherever the road takes you — with automatic shut-off, a 40" 90-degree twist-on chuck for easy access, and long air hoses to reach all your tires.

3. Simple, Safe Winterization
Use the included Viair Winterization Kit to easily blow out your RV’s water lines and prevent costly freeze damage. Designed to pair perfectly with your Viair compressor, it’s the quick, do-it-yourself solution every RVer needs.

4. Built for RVers, Tested by RVers
Trusted by full-time travelers and weekend adventurers alike, Viair products are field-tested by the MobileMustHave team — because we only sell gear we use ourselves.

⚙️ 400P-RVS vs. 450P-RVS — What’s the Difference?

Both compressors share the same rugged design and RV-safe automatic shutoff features. The main difference comes down to power and runtime:

• 400P-RVS – Ideal for most Class B and Class C motorhomes. Fills tires up to 150 PSI with a 33% duty cycle, meaning about 20 minutes of continuous use before rest.

• 450P-RVS – Perfect for larger rigs or those running higher tire pressures. Same 150 PSI max but a 100% duty cycle, allowing continuous use without cooldowns.

If you regularly inflate multiple large tires or want maximum runtime and durability, go with the 450P-RVS. For standard RVs or moderate inflation needs, the 400P-RVS offers excellent performance at a lower cost.
