I assume since grey/black must handle driving full.
Ofcourse when not concerned about truck capabilities.

Anytime you are towing, avoid fluids in any tank if possible. First reason is tow weight, second reason is potentially hundreds of pounds moving around can break tanks, and non-zero probability could cause an accident. If you are on the way to a boondock site, find a place as close to the site as possible to fill water on way in and dump tanks on way out. I do carry a very tiny amount just in case we need to use our washroom.
