I have seasonal camped for 16 years (towing is new to me). I camped in one spot from May until October. All waste had to be dumped via a tote. The campground I stayed in had approx. 50 seasonal campers ALL used THE campground's portable tote WEEKLY!
The campground always got the
Tote-N-Stor 25607 Portable Waste Transport 15 gallon capacity. The smaller size makes it more manageable.
You can see that with the "towing Bracket", you can hang it on your hitch and drag it to the dump station.

The campground had rough crushed stone roadways and this thing got used 50 times per week and held up VERY WELL.
I will be buying one for my new camper.
