We bough this RV 6 months ago from a dealership who didnt bother to tell us the black tank was FULL…we put it in storage for months not knowing we had a tank of 💩 sun drying in the florida heat…needless to say weve had issues with it since and this makeshift tool is the only thing thats worked! #rvlife #fulltimervliving #rvliving #rvtips #rvblacktank #blacktankflush
