Best Composting Toilet for RV: Capacity, Coir and Real Cost
The OGO Origin leads: urine-diverting, 25-30 uses per bin, 12 V agitator, no water. Plus bagged units, dry flush alternatives and the running costs.
Best RV Toilet Paper (and Whether You Need It at All)
You do not need RV-branded paper. Any 1-ply septic-safe tissue that breaks apart in ten shakes of a jar is black-tank safe. Picks, and the test.
Best RV Bidet: Attachments and Sprayers That Fit RV Toilets
Household bidets tee off a toilet tank an RV does not have. Fit an RV-specific attachment like the Clean Camper Original, or a sprayer on the 1/2 in line.
