When it comes to RV living, few things are as critical—and as dreaded—as dealing with the sewer system. Having a reliable, durable RV sewer hose can make the whole process easier and less stressful. For years, the Camco RhinoFLEX Sewer Hose has been a popular choice. But Camco took things up a notch with the RhinoEXTREME Sewer Hose, designed to last longer, handle rough use, and give RV owners greater peace of mind.
In this review, I’ll cover the key differences between the RhinoEXTREME and RhinoFLEX, share our personal experience, and help you decide which hose is best for your setup.

Our Experience with RhinoFLEX vs. RhinoEXTREME
When we first started RVing, the parts person at the dealership helped us with our initial purchases of everything we’d need. One of his recommendations was the Camco RhinoFLEX Sewer Hose, so we took his advice and bought it.
For the first six months, it worked fine—until it didn’t. After countless hookups, disconnections, and storing it for travel, the hose began to crack between the ridges and eventually started leaking. That was all it took for us to start looking for something more durable.
That’s when we discovered the Camco RhinoEXTREME Sewer Hose. For a little more money up front, we got a lot more value. Our very first RhinoEXTREME hose lasted us five years before it finally needed to be replaced. For full-time RVers like us, that durability makes a world of difference.
Buyer’s Tip: Why Spending a Little More Saves You Money in the Long Run
When you’re just starting out in RV life, it’s tempting to go for the cheapest sewer hose. After all, it’s not the most glamorous piece of gear. But here’s the truth we learned the hard way: a cheaper hose may end up costing you more in the long run.
With the RhinoFLEX, we had to replace it after just six months because of cracks and leaks. That meant extra expense and extra hassle while on the road. Compare that to the RhinoEXTREME: our first one lasted five years of full-time use before needing a replacement.
By spending a little more up front, you get:
- Longer lifespan – fewer replacements mean fewer purchases.
- Less stress – confidence your hose won’t fail when you need it.
- Better performance – smoother interior, crush-resistant durability, and easier handling.
If you’re serious about RVing—or even just camping regularly—investing in a RhinoEXTREME sewer hose can save you money, time, and frustration down the road.
RhinoEXTREME vs. RhinoFLEX – What’s the Difference?
The key difference comes down to construction material and durability:
- RhinoEXTREME Sewer Hoses
- Made with Thermoplastic Elastomer (TPE), a rugged, flexible material that resists abrasions, punctures, and crushing.
- Holds up in rough conditions—dragging across gravel, being stepped on, or stored in tight RV compartments.
- Keeps its shape and integrity even after years of use.
- RhinoFLEX Sewer Hoses
- Made from polyolefin with steel wire reinforcement.
- Durable for light use, but prone to cracking or splitting over time, especially in cold weather.
- A good option for occasional RVers but less ideal for full-timers.
In short: RhinoFLEX is good. RhinoEXTREME is better.
Comparison Table: RhinoFLEX vs. RhinoEXTREME
| Feature | RhinoFLEX | RhinoEXTREME |
|---|---|---|
| Material | Polyolefin with steel wire reinforcement | Thermoplastic Elastomer (TPE) with crush-resistant exoskeleton |
| Flexibility & Storage | Collapses easily for compact storage | Compressible, but holds shape better under pressure |
| Durability | Good general durability, but can crack or crush | Superior durability—resists crushing, abrasion, and splitting |
| Fittings & Accessories | Swivel fittings, clear elbow, 4-in-1 adapter, caps included | Same high-quality fittings and accessories included |
| Ideal For | Budget-conscious RVers, weekend camping | Full-time RVers, frequent use, rough campsites |
Key Benefits of the RhinoEXTREME Sewer Hose
- Superior Durability – TPE resists pinholes, cracks, and leaks.
- Crush-Resistant Strength – Bounces back if stepped on or driven over.
- All-Weather Flexibility – Won’t stiffen in cold or get too soft in heat.
- Smooth Interior – Helps waste flow efficiently and rinses easily.
- Fitting Compatibility – Works with RhinoFLEX gear for easy upgrades.
Available Lengths and Kits
Both the RhinoFLEX and RhinoEXTREME hoses come in different lengths to fit your rig and campsite setup:
- 10-foot hoses – Great for short runs or secondary use.
- 15-foot hoses – The most popular and versatile length.
- 20-foot hoses – Perfect for larger RVs or when hookups are far away.
Camco also makes extensions that connect with your existing fittings, giving you flexibility when you need more reach.

Our Recommended Setup
Through trial and error, we’ve found the best combination for flexibility at any campsite:
- One 10-foot hose – For close sewer hookups.
- One 15-foot hose – The most versatile all-around option.
- Two 2-foot extensions – Handy when you just need a little extra reach.
This setup gets us up to 29 feet of reach, more than enough for most of the campsites we’ve stayed in over our 6+ years of full-time RVing.
Along with hoses, it’s smart to carry a variety of connectors. Elbows, clear adapters, and Y-connectors make it easier to hook up at oddly placed or multi-port dump stations.
This setup has worked well for us in just about every situation, from tight full hookup sites to long reaches at dump stations.

Which One Should You Buy?
If you’re still undecided, here’s the quick answer:
- Choose RhinoFLEX if…
- You’re a weekend camper or occasional RVer.
- You want a budget-friendly option.
- You don’t mind replacing it every year or two.
- Choose RhinoEXTREME if…
- You’re a full-time RVer or camp often.
- You want a hose that lasts for years.
- You’d rather invest a little more up front to avoid leaks and cracks.
For us as full-time RVers, the RhinoEXTREME is the clear winner. It’s tougher, lasts longer, and has given us peace of mind every time we hook up.

Camco Rhino RV Sewer Adapter PRO – Clear Elbow with Drain Lock
One of the best add-ons for your RV sewer setup is the Camco Rhino RV Sewer Adapter PRO.

- Universal fit – works with 3-inch slip connections and 3- and 4-inch threaded sewer inlets.
- Drain lock adapter – locks in place for a secure, leak-free seal.
- Durable construction – built with Rhino’s tough plastic designed to handle repeated use.
