Re: [A/S] Frame/Body Seperation

[Charlie/Betty Burke <cbburke@xxxxxxxxxxxxx>]

There are two frame separation service bulletins. Bulletin #1 "Shell to 
Chassis Separation" dealt with an actual separation of the body from the 
frame at the rear of the coach caused by load spreading spacers/washers 
at the lower body perimeter rail to frame junction pulling through the 
perimeter rail where it crossed  the frame at the back end. It is 
evidenced by a gap between the frame and the lower body trim at the 
point where the frame extends out from under the coach at the rear. This 
bulletin applies to 1968-1972 models.

The second bulletin, #29, had to do with the frame aft of the axles 
actually bending from the overload caused primarily by the addition of 
the gray water tank. The original frame, typically on the longest 
coaches could not support a full load of liquid in both the gray and 
black tanks over rough roads. Or in some cases a hard bounce or two 
seemed to be enough. This applied to coaches from 1973-1976 when 
Airstream added a reinforcement to the frame.
