I'm more curious on how your RV dealership responds to your phone call
I have filled my blank tank with water and soap on occasions soaking overnight, let it slosh around on the way to the CG, and then dump it upon arriving at the CG.
You mentioned the TT was in service recently for "a leak", what kind of leak?
