Camco RhinoEXTREME 20-ft Sewer Hose Kit (39867)

Published · Researched 2026-09-21

2026 lineup note: SKU 39867 is the current RhinoEXTREME 20-ft kit in 2026 — $112.99 direct from Camco (crawled ~2026-09-17), also ~$91–93 on sale at Target/mygreenoutdoors. The 15-ft kit is 39861. RhinoEXTREME is Camco's TPE (thermoplastic elastomer) sewer-hose line — the step-up sibling to the RhinoFLEX polyolefin line (39742), not a replacement. No 2026 successor found.

Version lineage (2023–2026)

• 39867 (20-ft kit): 2 × 10' TPE hose sections with pre-attached Rhino swivel bayonet and lug fittings, transparent elbow with 4-in-1 adapter, 4 storage caps — unchanged through 2026.
• 39861 (15-ft kit): the smaller sibling.
• Smart-buy advice: the 20-ft kit is the full-timer standard; the 15-ft kit suits smaller rigs and tight storage. Both use the same TPE hose.

Overview

The RhinoEXTREME is Camco's answer to the RhinoFLEX's known weakness: the FLEX's polyolefin hose eventually cracks and splits (especially in cold weather), while the EXTREME's TPE hose is crush-proof, abrasion-resistant, and holds its shape for years. It costs roughly 2× the RhinoFLEX 20-ft kit — and the full-timer community's verdict is that it pays for itself by not needing replacement. Pre-attached swivel fittings, a transparent elbow with 4-in-1 dump-station adapter, and storage caps make it ready to use out of the box.

Warranty

UNVERIFIED — Camco's warranty terms for the 39867 could not be confirmed from a primary source during this research. (The RhinoFLEX 15-ft kit's Amazon listing states "Limited 1 Year" — do not assume the same for RhinoEXTREME; confirm with Camco.)

Support & Parts

• Camco (Greensboro, NC) handles support; reusable locking rings and replacement caps are the consumable parts.
• Fittings are pre-attached but the locking-ring design allows moving fittings to a new hose.

Community Verdict

The full-timer review that defines this product is GoFullTimeRVing's: their RhinoFLEX lasted six months before cracks and leaks forced replacement; their first RhinoEXTREME lasted five years of full-time use before needing replacement — "by spending a little more up front, you get longer lifespan, less stress, better performance." The material science is the whole story: TPE resists abrasion, punctures, and crushing (stepped on, dragged across gravel, stuffed in tight compartments) where the FLEX's polyolefin-with-steel-wire eventually splits, especially in the cold. Owners praise the smoother interior (better flow, easier rinsing), the way it holds its set shape, and the secure pre-attached swivel fittings. Target's review base is small but positive (4.7★, 3 reviews, older). The consistent framing: "RhinoFLEX is good. RhinoEXTREME is better" — and the price premium (~2× the FLEX kit) is the only real objection.

Long-term durability & warranty-claim reality

• 5-year full-time replacement cycle is the documented anchor (GoFullTimeRVing) vs. ~6 months for a RhinoFLEX under the same use — the durability delta is the product's reason to exist.
• TPE cold performance: the FLEX's failure mode is cold-weather cracking; TPE's flexibility in the cold is the specific upgrade (no lab data found — owner-reported).
• Fitting longevity: pre-attached swivel fittings with reusable locking rings; no pattern of fitting failures found in the sources reviewed.
• Abrasion/puncture: "superior abrasion resistance for maximum protection against pinholes and leaks" is Camco's claim; the full-timer 5-year run is the field evidence.
• Warranty-claim reality: UNVERIFIED — no owner warranty-claim narratives found in this research pass.

Version history — year by year

• Pre-2023: RhinoEXTREME line established as the TPE step-up above RhinoFLEX.
• 2023–2026: 39867 unchanged; pricing holds ~$91–$118 street. The FLEX-vs-EXTREME debate resolves increasingly in EXTREME's favor among full-timers.

Head-to-head vs closest rivals

• vs Camco RhinoFLEX 20-ft Kit 39742 (in this catalog): the in-family debate. FLEX: cheaper (~$50–60 street), thinner 23-mil polyolefin, 6-months-to-years life. EXTREME: ~2× the price, TPE, years-long life, better cold performance. Occasional/weekend campers do fine with FLEX; full-timers and cold-weather campers should buy EXTREME.
• vs Camco RhinoFLEX 10-ft Extension 39764 (new in this catalog): the extension's bayonet fittings are the standard Rhino interface — it extends either kit. (Cross-compatibility of the FLEX extension with EXTREME fittings is highly likely given the shared bayonet standard, but UNVERIFIED from Camco — confirm before relying on it.)
• vs cheap "starter" hoses: the unanimous community advice — owners who start cheap upgrade to RhinoFLEX within a season and to EXTREME within a few years; buying EXTREME first is the cheapest long-run path for serious RVers.

Care & maintenance

• Rinse thoroughly after each dump; cap both ends before storage (caps included).
• TPE tolerates tight coiling better than polyolefin, but avoid kinking at the fittings.
• Inspect the transparent elbow for cracks — it's the most exposed rigid part.
• Store capped; the removable 4-in-1 adapter allows 4" square bumper storage.
• Keep locking rings snug; they're reusable by design.

Buying traps

• FLEX vs. EXTREME packaging: similar orange Rhino branding — check the SKU (39867) and the "TPE" marking, not just the color.
• Price: ~2× the RhinoFLEX kit — the premium is real; match it to your usage (full-time/cold = worth it; twice-a-year weekends = FLEX is fine).
• 15-ft vs. 20-ft: 39861 (15-ft) vs. 39867 (20-ft) — the 20-ft kit's two 10' sections let you use just 10' at close dump stations.
• Warranty UNVERIFIED: don't assume the FLEX's 1-year terms transfer.
