We haven't had the joy of viewing others dumping their tanks while we await our turn, if there are more than a couple of rigs ahead of us we will dump on the way back whether at truck stops, convenience stations, or private rv parks along the highway. We can dump at home as a last resort, and have also done the last day at an RV park where full hookups were available. I guess we are fortunate as there are several gas stations within a five mile radius that have free dump stations. We do have a macerator onboard but it rarely gets any use, we have our system for dumping tanks that is much quicker by far.
