Just be sure the campground actually has a dump station before filling the tote.
Many years ago, I bought a 15 gallon tote. I used it once, at home, to clear the tanks while winterizing.
After that, it occurred to me that the RV parks/campgrounds we are most likely to use either have full hookups or no hookups, no dump station, and no garbage service.
After the tote sat under the workbench for five years, I sold it in a rummage sale for $15 just to get it out of the way.
With no place to dump it while camping, IMO the thing was useless.
Plan ahead.
