We just got a 42 gallon tote and LOVE it. However, our situation is a little different. We own a lot in a private campground with water and electricity but no sewer. We have two 38 gallon gray tanks and a 38 gallon black tank. When we first purchased the lot, we had a small tote and my poor hubby would spend a couple hours dumping the tanks (and we didn't shower in our FW because of it). Now, we make three trips which take about half an hour. He pulls the tote and hooks it up to our quad or truck and off we go. And the tote has rubber wheels which is great for the gravel roads of our campground.
When we had the smaller tote and traveled, we kept it in the bathtub. Not sure where you could put the 42 gallon one though.
