New owner of 2000 XL. It's an 8-12 bunk bus that's really well maintained. The black/grey tank dump system requires you to pull over a grate to release a valve to dump the tank. It seems to be the norm in the band busses I looked at. I'm having a hard time finding places that allow this type of dumping. I live on the Gulf Coast in Gulf Breeze, FL near Pensacola. Wondering if I should convert system to standard RV bayonet valve and hose set up. I intend to stay in some campgrounds and am just about to take my first road trip in the bus. New to all this and appreciate any help. Dave
