there is enough width in the spot where the rv pad is going to be for a second coach i think. and can always T off of the septic rv drain. wont really know till things get put in for the septic tank. i will ask the septic tank guy about the need for a separate vent. if the rv dump can go into the septic tank separately, then the venting from the shop will probably provide a place for air to escape. i looked online and it does appear that most septic tanks have 2-3 spots to connect piping into on the entrance side of the tank.
