Water storage ideas/suggestions?

[mark]

I don't store ro/di other than the few gallons in the reservoir that came with the unit, nor pre-made up SW.

Every couple or 3 weeks for a water change I just fill up a trash can with ro/di and then go from there.

I've been thinking as well as getting a RV tank since first seeing the one in my trailer just haven't really looked for one. I have a basement fish room and the flat profile of the RV tanks would make it easy to suspend from the floor joists without worrying about hitting my head. That way I could use gravity for a ATO and the tank wouldn't take up any floor space.

If I ever stumble across that RV wreaking yard that people keep telling me about but don't seem to know the name, I'm buying one.
