P32 Chassis

I read here often about the P32 chassis. I'm curious to know which AS/MH's have them. Were they used on specific models, options, years??

Thanks.

345Bill, I Google Work Horse P32 and was surprised. From what I read all RV chassis from GM were P32 which would include AS, and that P30 is more of a model reference. At that web site Barth MH forum listed there, has alot to say about the diffferences between P30 and P32.
So if I'am under standing it right, all years AS MH are included and built on the P32 chassis.

gloran- You're not alone in being surprised. Every time I think I have it half way understood I find something else that throws a curveball into my thoughts. I haven't had any problem when ordering parts for my 1990 345LE and I've always told the parts people it's a P30, which is what I was told when I originally purchased the MH.

So....I'm now kinda thinking most AS/Mh's are on a P32 and the 345's use the P30? (that thought could easily change)

P30 seems to as mentioned be a catch all for the Chevy frame we all enjoy.

In fact the VIN is the key to parts. I had to get up from my easy chair to check the visor and in fact my 1987 28' FC is a P37.

As far as I am aware the MH came on a P32 chassis which was a MH version of the P30, there were several different wheelbase lengths, although much of the literature and service manuals refer only to the P30. I think that in some instances there were a very few parts which were MH specific rather than just plain old P30 parts...

Chuck - does this seem right to you?

OK! ....mmmm...... Yes! it's clear - well nearly.............. as mud!!!!

As usual... any model numbers, chassis numbers, production numbers, what ever you like, are not logical.

P-30 (P-300) is a series with various other models P-32,P-42, P37 etc referring to mods, updates different weights etc, it is quite lengthy but perhaps the following thread/discussion below will help - its not worth writing it all out again but the info in this article is very informative.

The P is for forward control, the 3 is a 1 ton weight series. Beyond that the mystery begins.

When I recently bought a center support bearing the book showed two different sizes. I knew from a recent discussion with a spring shop that the motor home chassis with 4 wheel disc brakes has larger diameter axle tubes than one that has drum brakes. So I said I need the larger bearing of the two. Naturally I took it back the next day to exchange for the small bearing.

I also own a 1979 5 series GM truck. The truck has a 3" drive shaft while the Moho has a 4" drive shaft. The differentials appear to be about the same size and both vehicles run 8x19.5 tires.

I think a lot of what they used was what their suppliers had shipped and was available for installation.

Cheers, Dan

Someone said it earlier in here, the key is your VIN numbers (characters 5-6-7) P30 is a chassis only, P32 is designated as forward control chassis, P37 (mine) is designated as a motor home chassis. BTW the 4th character denotes the gvwr-brake system (K=14000-16000lbs, hyd. brakes) and the 8th character is the engine (N=7.4L tbi) these codes are from a '88-90 repair manual and may vary slightly in different years but i believe the position in the VIN number is the same.

The 370 MH is built on a Gillig chassis with a Ford 460 drivetrain. It's the only AS classic MH I know of not on a P-30.

Thanks.
I'm afraid I cannot tell you exactly which ones have the P32, however, I found this handy little table on page 7 of a "Workhorse Gas Motor Home Chassis Guide" that I downloaded from the internet. It covers years '99 and newer. Just match your VIN with the corresponding position #'s at the top of the page. Our 2005 AS LYG 30 SO has a P32. Hope this helps.

Maybe Workhorse has similar tables for older P series chassis as well.
