Service Manual 2004 Workhorse P32 chassis

[Tim Nadaud]

Hello, I have a 2004 Itasca Sunova 27C P32 Workhorse chassis 8.1 Vortec engine with a 4L80E transmission. I am looking for a service manual for this RV. Any help would be greatly appreciated.
Thanks
Tim

In general... there are no service manuals for any of these RV cut down chassis available to the public. Still to this day, Service Manuals for Ford F53 cut down chassis are not available to the public.

Workhorse Dealers may have been able to get such a thing. But you'll be better served by chasing down such a service manual from GM sources for the engine, Alisson sources for the transmission and any Ex-Workhorse manufacture or repair facilities.

I don't believe any Winnebago dealer ever had such a manual either.
Good Luck.

appears to have engine and transmission service manuals pdf downloads for $25.

All of the Workhorse manuals were available on a Navistar/Workhorse for free, until just a month or two ago.

Looks like the Internet Wayback machine has as snapshot, but didn't archive the whole site? I don't use the Wayback machine much. Maybe some knows of another archive?

The old Barth MH forum library has a few different workhorse chassis service manuals. These chassis are basically GM 1T truck chassis.

The library is unsorted so grab a cup of coffee before beginning to peruse their library.
