My current 5th wheel will drain about 85% of the water from the WH if I open the low point drains. It really depends on how they routed the plumbing from the factory. I have to remove the anode rod to get the last 15% out. Even then, about 5% stays in the tank with the anode rod removed. To totally drain, I have to insert a small hose and siphon the last little bit out.
If you are just wanting to drain the majority out just for the down time between uses, I would open the low point drains, open a hot & cold tap, let the system empty, remove the anode rod/plug and see how much remains in the tank. If you are satisfied it empties 75-85% of the WH capacity, I wouldn't be taking the anode rod/plug out each trip after that. Just my 2¢.
Winterizing... different story.
