Wow GordonThree! I'm impressed! Someone actually listened to something I suggested. What a compliment that is!
That's a pretty cool tank, isn't it! I do know I really like ours. Just for an fyi, mine has never slide around in the back of the truck bed. I keep it as near the tail gate as possible since I have a shell over the bed. It's never moved with water in in. but usually, I've got stuff packed around it too. Empty, it's slid around when I've applied the brakes hard, of course.
Ours has sure served a need, I'm sure yours will to. I normally do not take too much effort to sanitize my fresh water tank on the camper. But in the Spring, I do add a bit of bleach to my TSC tank and flush it out real good. Don't know if it's really necessary, but it just makes me feel a bit better.
