Buying Guide: Key Purchase Considerations

- Maintenance and sealing: Detachable waste tanks and leak-proof designs reduce spills. Check for level indicators to time dumps accurately.
- Compatibility: Some toilets fit standard RV plumbing, while tote tanks require compatible hoses and adapters. Verify space and flange compatibility before buying.
- Installation complexity: Fixed toilets may need professional setup, while portable options emphasize simplicity and disassembly for storage.
