I did this video on a 2004 Roadtrek Popular 190 but it should be applicable to the Chevy Versatile and Popular 170 as well. Roadtrek always stuck with their concepts for the long term so it may cover 1990 vans through 2020 which I believe will be the last year of the Chevrolet if they built any before the change in ownership. And remember, if you can wash a head of lettuce with it you can probably use it for an RV shower because a human also has a head. That is solid Canadian logic.
I added a note to the bottom of the video with some additional steps for the city water fill valve. This is probably the last Coach video for the year unless something comes up. I do need to change the oil pan gasket, oil cooler gasket, change both serpentine belts, and do some other chassis work...hopefully before winter.
