Full Spec Comparison
Both tanks target the same buyer: an RVer who needs to move waste from a site without a sewer hookup to the dump station. The 36-gallon size makes sense for families and larger rigs that fill up fast. Here's how every measurable spec stacks up:
| Spec | Camco Rhino 36-Gal | RecPro 36-Gal | Edge |
|---|---|---|---|
| Price (Amazon) | $297.65 | $349.95 | Camco — $52 less |
| Material | UV-stabilized HDPE | Heavy-duty Polypropylene (PP) | Camco — HDPE is more UV-resistant outdoors |
| Dimensions (L×W×H) | 46″ × 25″ × 15.5″ | 44.5″ × 24.75″ × 15″ | Essentially identical |
| Empty weight | 45 lbs | Not published | Camco — transparent spec |
| Full weight (36 gal) | ~345 lbs | ~346 lbs | Same |
| Wheels | No-flat airless tires | No-flat airless, diamond-pattern tread | Both airless; RecPro tread may grip better on grass |
| Capacity indicator | None | Yes — built-in | RecPro — useful feature |
| Fill port | Threaded cap, top inlet | Large open-top port | RecPro — easier to fill and rinse |
| Included accessories | Sewer hose, 4-in-1 adapter, elbow, caps | Sewer hose, gloves, caps, capacity indicator | RecPro — gloves included |
| Assembly required | Minimal — wheels pre-attached | Fully pre-assembled | RecPro — ready out of box |
| Warranty | 2 years (published) | Not listed on Amazon | Camco — clear coverage |
| Review count | 27,262 reviews | 106 reviews | Camco — vastly more field data |
| Rating | 4.7★ | 4.3★ | Camco |
| Ladder hook storage | Yes | Not confirmed | Camco |
| Best Seller badge | Yes (#1 in category) | Yes (#2 in category) | Both bestsellers |

Material: HDPE vs Polypropylene
This is the most technically meaningful difference between the two tanks. Both are industry-standard waste-grade plastics, but they have different properties in outdoor RV use:
| Property | HDPE (Camco) | Polypropylene (RecPro) |
|---|---|---|
| UV resistance | High — UV stabilizers added | Moderate — degrades faster without UV additives |
| Impact resistance | Very high — resists cracking when dropped | Good — slightly more brittle in cold |
| Chemical resistance | Excellent for waste water | Excellent for waste water |
| Density / weight | Slightly heavier per cubic inch | Lighter per cubic inch |
| Long-term outdoor storage | Better — UV spec confirmed | Fine if kept covered or shaded |
Accessories: What's in the Box
The accessories differ enough to be a real purchase factor, depending on what you already own:
- 3-foot sewer hose
- 4-in-1 dump station adapter
- 90° elbow fitting
- Threaded caps (inlet + outlet)
- Ladder hook for RV storage
- Tow bar / handle
- Sewer hose
- Disposable gloves
- Caps (inlet + outlet)
- Built-in capacity indicator
- Pre-assembled — nothing to attach
- Open-top fill port
The Camco includes a 4-in-1 dump station adapter that the RecPro does not — that's the adapter that fits four different common dump station inlet types. If you don't already have one, you'll need to buy it separately with the RecPro. The RecPro includes gloves, which Camco does not — a nice touch for first-timers, though most experienced RVers have their own.
RecPro's Capacity Indicator: Is It Worth It?
The built-in capacity indicator is the RecPro's most distinctive feature and the primary reason someone would choose it over the Camco. A 36-gallon tote tank weighs around 345 lbs when full — you do not want to discover it's at capacity by having it overflow or become immovable partway to the dump station.
Open-Top vs Threaded Fill Port
The RecPro uses a large open-top port for filling and rinsing — you can rinse directly with a standard garden hose without adapters. The Camco uses a standard threaded cap inlet. In practice:
- The RecPro's open port is faster to fill and easier to flush out residue during cleaning
- The Camco's threaded cap is more secure if the tank tips — the closed system prevents spills from a capped inlet
- Both handle the emptying process identically via the gate valve and sewer hose connection
Price Analysis: Is the RecPro Worth $52 More?
At $349.95 vs $297.65, the RecPro costs about 17.5% more. The extra cost buys you: a capacity indicator (useful), gloves (minor value, ~$5), and the open-top port (genuinely convenient). Whether that's worth $52 depends on how much you value not guessing your tank level.
Who Should Buy Each Tank
Buy the Camco Rhino 36-Gallon if:
- You want maximum peace of mind from a proven product (27K+ reviews, 4.7★)
- You want an explicit 2-year warranty
- You'll store the tank outside in direct sun for extended periods
- You want to save $52
- You already own a dump station adapter and gloves
- You don't need a built-in level indicator (most experienced RVers don't)
Buy the RecPro 36-Gallon if:
- A built-in capacity indicator would genuinely change how you use the tank
- You prefer the open-top port for easier filling and rinsing
- You want a fully pre-assembled tank with zero setup
- You like having gloves included in the kit
- The $52 premium is immaterial to your budget
