Over heating -- followup and question

[Pete Masterson]

Picked up my coach from the radiator shop a couple of hours ago. When
I arrived, the shop had it idling and all warmed up. Upon looking at
the breather tube, I could see a fine mist being expelled... and
drifting under the radiator and back through thanks to the air
currents with the fan. Looks like an extension on the breather tube
would be an excellent idea to reduce the tendency to build up the oil-
dust mixture.

Question about the AC system (not the roof ACs): The radiator shop
also services AC systems and found the AC had 'zero' freon (134a).
The coach had sat for 6 months from the time it was traded in until I
bought it. While the dealer may have started it up from time to time,
I doubt that was very frequent -- and he may not have turned on the
AC. So, I presume that a seal in the system dried out and allowed the
refrigerant to escape. The shop, after loading 9 lbs of 134a, was
unable to find any leaks in the system --- but had no access to the
lines from the rear to the front of the coach as they are hidden
somewhere as they run along the coach frame rails. Are there any
likely leak spots between the front and rear of the coach? Where
would I look to trace the AC lines? Does anyone have any comments
about keeping the "automotive" AC working? (I don't expect much from
it, but a little cool air up front while on the road would be nice --
especially when the sun is beating in the window.)
