I am now ready to do my AS plumbing. Here is what I have:
1. Re-painted orignal
1963 Overlander bathtub.
2. New Aquamagic V toilet
3. New 8 gallon black tank.
4. Original sinks with updated faucets.
Need to buy everything else...
~ I will be 99.9% hooked to city water & sewer.
~ I need to find out how to get bathtub to drain to an exit valve.
~ I need to configure kitchen & bath sinks to drain out same valve.
~ I need the proper black tank valve
I really want to do this without a gray tank.
Question.
? Can I do this without a gray tank?
? Is there a site and/or resource wherein I can get a list/diagram to re-create this pluming without "re-inventing the wheel"?
? A supply house that can sell me all the connectors, valves, fittings I will need?
Thanks AirAngels

for your input. Never would have gotten this far without this site.
FYI- All cabinets/walls etc are out of the trailer- I can configure any which way at this point. Futhermore- I am not not against using a shower pan if that helps the situation. Not attached to the tub...
Peace,
