Yes, do it just like you did on your previous campers. You don't need to winterize the black tank flush but it won't hurt to blow air through it. There isn't a check valve, only a vacuum breaker and the water usually drains out through the spray nozzle and the outside connection.

If you don't bypass the water heater you will need more than 6 gallons of antifreeze to winterize. Just drain it by letting it cool down and remove the drain plug after you turn the bypass valves. If you have a Suburban WH winterizing is a good time to inspect the anode. Just put it back in with teflon tape wrapped on the threads when your done to keep the creepy crawlies out. The anode/drain plug on the Suburban is 1=1/16". Atwood has a 7/8" drain plug.
