Rick,
In the manuals section is there a manual for an 89 P30?
For Chevy P30 we have the Chevy Motorhome Service Guide in the Members Free Manuals section of the web site. The other manuals would be Winnebago Operators style manuals for the rig.
GM elected to produce separate Service/Repair/Wiring manuals for each year model so there are lot of P30 manuals (hosted with pickup data under light trucks). Please refer to this post which tells you haw to locate Chevy P30 manuals.
http://www.classicwinnebagos.com/forum/index.php/topic,4974.0.htmlDo not confuse Chevy S-10 manuals with R-V-P 10-30 Series Light Truck Manuals. You do not want S-10 manuals.
In the mid 90's GM broke out the P32 manuals into their own books (not mixed in with pickups)
And finally, around 1997 GM sold the P30 chassis to Workhorse Corp. which produced variants of the P30 chassis until GM stopped producing the 8.1L gas engine a couple of years ago. The P30 chassis era is now dead and gone. There is no longer a GM based Class A gas motorhome chassis produced. The P30 Series did enjoy a long life though as it dates back to the early to mid 70's.
Currently the only new gas based Motorhome chassis is the Ford F53 (ramped of the Ford F-550) which was first produced in the early 90's. I have a sneaky suspicion it was born of the John Deere/Oshkosh chassis which was a Ford based powertrain (460).
I have heard Freightliner/IH/Oshkosh just might produce their own gas based chassis though.
