If there's a line, I'll get out the tote with the hose, etc and have my kids put it near the dump station while I'm waiting in line, and start getting all the stuff out. I get out, hook up the hose, flush black and grey while the kids are filling up a bucket. As soon as the hose is disconnected, I pull forward while my kids put the hose back in the tote and catch up to me with the bucket and the tote.. I then put stuff away and dump the bucket in the toilet with the chemicals at my leisure so that I only spend time dumping at the dump station.
Even without a pit crew, there is some pre-work and post-work that can be done away from the dump station so that you don't spend time doing it all while people are waiting.
