My tote is designed to be towed so I tow it. I can't see it so I roll the window down and just listen. I always get waves from old timers. I drive along at 5 mph and have never had a spill - including black water. I'm of the opinion that using the tank is far less trouble than breaking down camp, but if people want to do that fine with me.
My tank gets the job done with minimal equipment. It may take more effort than a pump, but I'm just not into that stuff.
Now sometimes the campsite is sandy making it hard to pull the tank to the hitch and once there was a slope where the tank sat a little higher than the TT connection, but hey, I'm camping and I see this as one of those things that needs to be done. Sometimes I'll dump the gray water into the tank so there is enough room in the tanks for showers/dishes, then haul it in the morning. After about a 30 minute job, I'm back to business as usual.
