If your coach still has the Coach A/C ducts along the edge of the walls and floor.
Look for 2- 4X6" access plates on each side of the ducts midway in the coach.
If the ducts have been removed then the previous owner could have put them any where or might have done away with them.
Good luck.

i have the the duck work that runs down the middle of the bus that hold alot of air lines and i believe a/c and heat lines ?? or are you talking about the inside of the bus along the floors not in tha baggage compartment??

Inside of the coach left and right side at floor level.
Not down in the baggage bin.
