I’m sure it has those tanks built in.
What I’m referring to are the waste toters that you can drain your tanks into, then attach the toter to your tow vehicle and take the toter to the dump. Saves having to hitch up and drive your RV to the dump, which is a major pain.
I forgot to mention that if you can, always tow it “dry” meaning don’t add water if you can and make sure you drain all of your tanks(potable, gray, and black) before you head home.
Helps a little with few mileage getting rid of a few hundred extra pounds.
