Top 5 Features That Make MAKS Plastics Tanks the Best on the Market

1. Seamless, Heavy-Duty Roto-Molding

MAKS tanks are manufactured using advanced rotational molding technology that creates a single-piece, seamless tank with uniform wall thickness. This eliminates weak points, seams, and potential leak areas that plague welded or multi-piece tanks.

2. Premium UV-Stabilized Materials Made for Real RV Conditions

Every MAKS tank is molded from high-grade polyethylene with UV inhibitors built into the material itself. This protects against sun exposure, temperature extremes, and chemical degradation from waste products, ensuring your tank won't crack, fade, or fail prematurely.

3. Precision-Engineered Fit for RV Chassis

MAKS doesn't make generic tanks. Each model is designed to fit specific RV chassis configurations with exact dimensions, drain placements, and mounting provisions. This means easier installation, better space utilization, and proper integration with your RV's existing systems.

4. Made in the USA With Full In-House Engineering

MAKS Plastics manufactures every tank in the United States with complete control over materials, processes, and quality standards. Their in-house engineering team designs tanks specifically for the demands of RV use, not generic applications.

5. Proven Long-Term Reliability & Lower Lifetime Cost

MAKS tanks are built to last decades, not years. The combination of superior materials, seamless construction, and precision engineering means fewer replacements, less maintenance, and lower total cost of ownership compared to budget alternatives.

RV Applications & Compatibility

  • Large motorhomes requiring extended waste storage capacity
  • Travel trailers for extended boondocking and dry camping
  • Fifth wheels needing substantial holding tank capacity
  • RV renovations and custom builds
