We saw the bottom of our first "empty" FW tank a few years ago. Hard to get that mental snapshot of slime/gunk out of our minds.
That must be "Factory" stuff.
Not only I could see water tanks in several RVs, but lately I parted old Lance and pulled the tanks for other uses.
When dump tanks did have some solids build ups, the water tank was perfectly clean even in my 3 years of ownership I recall draining it only once.
But I live in dry climate, where even I've been checking for algees in tanks, including diesels, have never been able see them.
Coming back to "factory stuff" during camper demolition I collected about 1/2 gal of sawdust, cut wires and package debris from camper cavities.
