Fresh Water Fill 

Would you consider a "how to drain the freshwater tank" video? I'm trying to be as prepared as possible before purchasing.

Is there a fresh water drain feature?

Anyone know of a funnel that works with the water tank fill port? I've tried to refill a casita from a 5 gallon jug, and the water wants to spill everywhere. I could make my own device by combining a funnel with some flexible tubing, but maybe there's a better way?
