IMHO I think the biggest difference is DO NOT let anyone where you park tell you to leave your black and gray tanks open to the sewer. My bet is sure enough that one or two of your new permanent neighbors will tell you to!
Leave them both closed until full, THEN dump.
Leaving the valves closed until full will prevent your tank from filling up with poop in the black and food stuffs, grease in the gray.
Dump the black first than the gray that will clean out the y pipe and sewer hose after you dump. Then close the valves. It will also prevent flies from getting into your tank too.
When you leave your valves open the poop just goes down and sits in the tank and makes a mountain of poop. You need water to move sewage out of a tank. Leave them closed!
Other than that if you've camped before it's about the same, except no rush to get back home you are already there!
Good luck on your new job.:C
