the air compressor is probably a gast.   that is what they used then.  it will keep your supply air pressure up when it is on.  so if you have any air powered things, like step cover, genny slide and to some extent your leveling system.  

on my 90 there was also a port to plug in an air hose.  

there should be a switch to turn it on either over the microwave or over the driver.  

to pump your tires up you will need an air doubler

in every air slide latch for the genny i have seen, it is in the upper part of the compartment that has the genny blower in it in front of the passenger side wheel.  at least on my 90, there was a choke cable with a knob on that released the catch on the genny, then an air valve with a round red knob on it to pull out to open the genny slide.  

if you can pull the genny out manually, either there is no air pressure in the genny slide cylinder or it is disconnected.  
how does it latch in?    when the air cylinder is working on the slide, it will also help hold the genny in.

Found the red knob in the right side gen blower bay, thought it might be an emergency shut off of some kind. The gen slide would not pull out at first, didn't realize it was air pressure related. The latch chain is apparently broken, I'll repair that. Thanks for the help
