You would have had a dish washing nozzle, it just connects to the water 
line behind the toilet, usually under the fiberglass shell - it varied 
by model & year.  The use of the spray nozzle is water conservation, 
but potable and black tank.  It uses 1/2 cup water to accomplish what 
takes 4-8 cups with a normal flush - adds up in a hurry.

It should hold water.  If it doesn't the flapper gasket is dried out or 
misaligned.  There is not just one easy fix - it can range from 
cleaning and reseating the seal, to "re-hydrating" the seal, to 
replacing the seal with a generic O-ring - or in some cases true 
replacement seals are still available as new old stock, etc.  It 
requires trips and calls to true RV parts and supply places (read: no 
Campers Choice or Camping World).  Pretty much true of all vintage 
parts.

Best of luck,
