Buying Guide

Choose capacity for your usage

Match tank gallons to your typical trip length—15–21 gallons suits short trips or solo use while 36 gallons reduces dump frequency for longer stays

Check tow compatibility and fittings

Look for robust tow handles, hitch-ready frames, and standard threaded fittings that work with your truck or golf cart tow setup to avoid on-the-road failures

Prioritize durable materials

High-density polyethylene and reinforced seams resist cracking and chemical wear; consider heavier construction if you tow frequently or over rough terrain

Evaluate wheel and axle design

Large pneumatic or heavy-duty wheels and a sturdy axle make it easier to tow loaded tanks across uneven surfaces and reduce strain on your pulling vehicle

Compare price vs. user rating

Balance cost with reliability: the Camco Rhino line consistently shows high user ratings (~4.6★) across 15–36 gallon sizes, indicating good value for price points
