Top 5 Features That Make MAKS Plastics Tanks the Best on the Market
1. Built With Seamless, Heavy-Duty Roto-Molding
One solid piece — no weak joints.
MAKS tanks are rotationally molded as a single shell, eliminating weld lines that crack, leak, or fail under vibration and temperature swings.
2. Premium UV-Stabilized Materials Made for Real RV Conditions
Designed to withstand heat, cold, road shock & full-time use.
The plastics MAKS uses resist UV fade, warping, odor absorption, and stress-fractures — outperforming "thin-walled" offshore tanks.
3. Precision-Engineered Fit for RV Chassis
Better geometry = easier install & greater capacity.
MAKS designs tanks to fit the tight spaces under modern RVs, creating more usable capacity while reducing install time and eliminating modification headaches.
4. Made in the USA With Full In-House Engineering
Fast service, reliable quality, and direct support.
Every tank is designed, molded, and quality-checked in Indiana. No outsourcing. No long supply chains. If something ever comes up, you get real support from the actual manufacturer.
5. Proven Long-Term Reliability & Lower Lifetime Cost
Buy once, not twice.
Cheaper tanks fail early from cracking, odors, or shape deformation. MAKS tanks are built to last years longer, reducing your total cost of ownership and eliminating surprise downtime.
