Thanks to all 3 of you for the helpful replies!
Jamie, We have a 35 gallon one left over from emptying the 37 footer's tanks! May have to consider downsizing it as well!
Underneath is a possibility, but it would probably need to be a smaller tote. Also, at our age anything accessed on our knees is usually a last resort!!
293, Had been contemplating the ladder! Could probably buy a smaller one to fit the pass through,too, but not the most sanitary thing to store with our chairs and other much used items!
28Z, Hadn't seen one of those! We've been eyeing the ladder, so I will check those out today!
Thanks All for the good suggestions!
